It is not currently possible with ifcfg-ethX... you can do it in a udev rule, or rc.local, or your own custom init script.

Don't know if it's related, but in a KVM-based install, if I first test the media, I have to disconnect and then reconnect the CD/DVD. From a physical install, a CD/DVD test should eject that media, IIRC.

RHEL 6 uses a different set of drivers for certain IDE/ATA chips, and apparently certain chips aren't properly supported any more in recent kernels. I'm thinking specifically of Intel 845 and 865 (I think; I'm sure of the 845), like used in Dell Dimension 4500S desktops. Fedora 14, 13, and 12 won't install on them either; older (pre-all ATA uses libata) works fine. Same error you see there. The CD-ROM is initially booted as a BIOS device, but once control passes from the initramfs to anaconda the access to the device goes through other channels, and for some reason those chips have issues with the new ATA stack. At least our Dell Dimension 4500S's have issues there; I wanted to use a Fedora liveCD to do a disk clone on one, and it would not boot at all; had to back up to an older version of SystemRescueCD (1.1.0; current is quite a bit more modern). So, try a number of LiveCD's and work up to where it quits working (use Fedora LiveCD's for consistency); start at FC6 and work your way up, and find out where it quites working. Need more info on your devices to help further. Also, check with Red Hat and see if your hardware is supposed to be supported.

There are a very very large set of hardware out there and trying to have a definitive list would be impossible to come up with. In general for these sorts of items you need to look at the following: 1) Can you get BIOS updates from the manufacturer. These may fix many issues. 2) Do you really need EL6 for this old of hardware.

Redhat 6 DVD installer has an anaconda error when we select either replacing the partitions or custom. Prior to selecting one of those options the installer produced this warning: Warning disks sda,sdb contains BIOS RAID metadata but are not part of any recognized BIOS RAIDsets. Ignoring disks sda, sdb. In one case the existing RAID had been created by RH5, and in another case of this install trial history, it had a RAID created by Debian 6. We can say OK to the warning, and try the default option to reuse and reformat the existing Linux partition, or chose the custom layout. Either way, there is an anaconda exception: anaconda 13.21.82 exception report Traceback (most recent call first) File "/usr/lib/anaconda/iw/cleardisks_gui.py", line 154, in getScreen selfbootDisk = sorted(names, self.anaconda.id.storage.compareDisks)[0] ...

It seemed unlikely RAID blocks could be present from that long ago, as we had these disks working as a Debian or Redhat 5 with software RAID 1. I used dd to wipe the first part of the drives with zeros and attempted the installation of RH6 from DVD again. Still saw the RAID metadata error. I wiped up to the first 5 GB of the disks, and no difference. Then I left dd running at the end of the day to write zeros right to the end of the drives. (WARNING: the following command wipes all data from disks, including partition tables...) # dd if=/dev/zero of=/dev/sda bs=8192 # dd if=/dev/zero of=/dev/sdb bs=8192 This morning I tried an install and no more errors about the BIOS RAID metadata. The RH 6 install completed and it boots fine as MD RAID 1. There are two flaws in the Redhat installer compared to RH 5 installer. The CDROM installation has problems seeing the very media it booted from, and the scan of the disk for existing RAID metadata has no way of saying lets force use of these disks despite finding some relic of RAID metadata on them. Debian 6 nor Redhat Enterprise 5 had problems reusing the disks while there was still some prior hint of RAID metadata. --Donald -------------- next part -------------- An HTML attachment was scrubbed...

This is how I understood it. suppose your nodes' hostnames are host1 and host2 suppose your nodes' intracluster names are node1 and node2 when you migrate a vm from host1 to host2, this is the command issued by default with qemu: virsh migrate --live guest_vm qemu+ssh://node2/system tcp:node2 so the ssh connection is done through intracluster (qemu+ssh://node2/system) and memory transfer is done through intracluster (tcp:node2) You can also verify this, comparing RX/TX bytes on interfaces before and after the migration (for example during a live migration of a RH EL 5 quite inactive guest with 2Gb of ram, I see about 250-300 MBytes transferred) This with a config inside cluster.conf such as Based on vm.sh in /usr/share/cluster I think you can only change both of them together (so both ssh link and image transfer link)... suppose your desired interface/bond device for migration is bound to these names: hostlive1 and hostlive2 I think you have to use the parameter migration_mapping with syntax like: memberhost:targethost,memberhost:targethost so that your cluster.conf line becomes: Not tried yet but it should work. You can see the meta-data for your resource agent with the command: /usr/share/cluster/vm.sh meta-data or walk through the script itself....

Keep in mind that you have also to: a) set up ssh root equivalence on the hostnames you are going to use for migration (hostlive1 and hostlive2 in my previous example) otherwise a command such as # clusvcadm -M vm:guest_vm -m node2 will get an error like this Trying to migrate vm:guest_vm to node2...Failed; service running on original owner and in messages: rgmanager[7861]: error: cannot recv data: Permission denied, please try again.#015 b) setup your firewall rules on both hosts to accept tcp connections in the range 49152:49215 from the other one ip chosen for migration otherwise it will fail with something like this in log file: Apr 15 10:48:56 host2 rgmanager[8387]: Migrate guest_vm to hostlive1 failed: Apr 15 10:48:56 host2 rgmanager[8409]: error: operation failed: Migration unexpectedly failed Apr 15 10:48:56 host2 rgmanager[2793]: migrate on vm "guest_vm" returned 150 (unspecified) (node the hostlive1, while by default you will see node1, aka the intracluster name) HIH, Gianluca From pm at bel.pl Fri Apr 15 09:33:21 2011 From: pm at bel.pl (Patryk Malina) Date: Fri, 15 Apr 2011 11:33:21 +0200 (CEST) Subject: [rhelv6-list] Migration between vms in AMD and Intel cpus In-Reply-To: <4DA7F742.5040603@gmail.com> Message-ID: <1414080460.11414.1302860001510.JavaMail.root@zimbra.bel.pl> Hi, Sure you can.

If I was in a similar situation, which I might be later as I try to add more different distros into kvm vms in my "library" I would try a different virtual network type. Like I see in virt-manager it says there are: ne2k_pci pcnet rtl8139 as well as virtio and e1000 types of adapters you can pick. I know nothing about these... I would try to install with all of those other types, one by one and see if any work, before I would give up. maybe one of them won't panic the guest OS? Then even if the adapter is the problem maybe this could work around it? I've only used virto and e1000. But I think the using e1000 was just a guess. My problems might have been random and a misconfiguration on my part and seem to have gone away recently even using virtio. But I also installed some weird stuff like gentoo and it worked ok until I broke it. (need to make backups with that distro I learned) Another thing to try might be the numbers? Like what happens if you just use 1 interface instead of 7? This is a all just guessing. Like I said I am a kvm noob.

I can substitute one e1000 interface with ne2k_pci or pcnet or rtl8139 ... but the others six, needs to run e1000 driver because is the only driver that supports 1GB. But I am thinking about to use two virtual e1000 interfaces only, and use VLANs to deploy the rest networks that I need in this guest. Can this will work?? Can i configure one vlan wih 4095 id like in vmware esxi does to see all vlans for a particular virtual bridge??

Or, for that matter, that virtio_net is limiting the speed to 1GB? You should find that guest to guest communication through virtual interfaces is limited by the performance of the host and guest to external machine is limited by the minimum of the raw machine performance and the physical NIC. Is this not the case? Here I get about 80MB/s between guests (admitedly using xen rather than kvm, but the principle is the same) even though the emulated NIC says 100Mb/s, which is rather less than the 700Mb/s I'm actually getting. (This is not a particularly quick machine either and in fact I'm limited by how quckly I'm pulling data off a disk, the maximum attainable speed without that is much, much greater). jch -------------- next part -------------- An HTML attachment was scrubbed...

No, I am not saying that virtual ne2k_pci or rtl8193 limit the bandwidth. I have test it. Using ne2k_pci or rtl8193, bandwidth is 1MB/s-850KB/s, very horrible ... Using e1000 driver bandwidth starts at 87-80MB/s at start and after some some seconds, bandwidth is degraded until is stalled, for example copying a 600MB file using scp ... But doesn't occurs for example using e1000 driver under vmware (workstation or esxi). Bandwidth is stable. -- CL Martinez carlopmart {at} gmail {d0t} com From allen at doobie.itdl.ds.boeing.com Tue Apr 19 18:58:32 2011 From: allen at doobie.itdl.ds.boeing.com (Steve Allen) Date: Tue, 19 Apr 2011 11:58:32 -0700 (PDT) Subject: [rhelv6-list] RHEL6 x86 on system with 4 GB memory In-Reply-To: Message-ID: <201104191858.p3JIwXRp011576@doobie.itdl.ds.boeing.com> "Jonathan M.

I'm in the same position, 4GB RAM, but no PAE in the BIOS, so all I get available is about 3.3GB.

First, you will notice two entries for memory in the KVM guest xml file. In order for memory to balloon up, the 'memory' parameter needs to be set to the max value you may ever wish to use. --- 4194304 2097152 --- In this example, the 2GB VM could expand upwards to 4GB, but no greater. CAVEAT EMPTOR: This requires the KVM guest OS to recognize a balloon memory driver! Many, do not. So the observed limitations are these: 1. You cannot modify the value of 'memory' without a reboot. 2. You cannot reduce 'currentMemory' without a reboot. 3. The KVM guest OS must recognize a balloon driver. The symptoms we observed of a non functioning balloon driver in the guest were these: The VM guest OS assumed 'memory' as available. The VM guest OS was limited to 'currentMemory' but did not recognize changes to 'currentMemory'. Guest VMs running Linux kernel 2.6.30 or better seemed to work, with the exception of Ubuntu 10.4. Fedora 12 and up all functioned properly.

I used a patched mrepo[1] to sync all the RHN channels locally and mrepo made them into standard yum repos for me. Some of the details and patches are on the following threads: http://darren.stanford.edu/serendipity/archives/138-mrepo-gensystemid-+-RHEL6.html http://lists.rpmforge.net/pipermail/tools/2010-December/001823.html http://lists.rpmforge.net/pipermail/tools/2010-November/001791.html /Brian/ 1. http://dag.wieers.com/home-made/mrepo/ -- Brian Long | | Corporate Security Programs Org . | | | . | | | .
