Resizing virtual machine harddrive in RHEL 5

[Geofrey Rainey]

Presumably you would have something like the following in your xen
configuration file for this host:

"Disk = [ 'phy:/dev/sda2, disk_name, w' ]"

I think you would need to build your guest system with the partition
disk_name as a logical volume, ie disk_name
Being a logical volume which one could then resize within the guest
system. I too have thought about 
What you are experiencing and to get around it I have had to create a
new partition within the host 
and present it to the guest like so:

"Disk = [ 'phy:/dev/sda2, disk_name1, w', 'phy:/dev/sda3, disk_name2, w'
]"

However, perhaps all this can be averted if the disk presented to the
guest is created as a logical
Volume as described above during the guest installation procedure.

Geofrey.

Subject: Resizing virtual machine harddrive in RHEL 5

Hi,

I'm running a virtual machine using RHEL 5 virtualization.  The virtual
machine has a hard drive image create has a file image on the host
machine.

Is it possible to increase the size of the hard drive or must I create
another disk image and mount it as a second hard drive?  I would prefer
being able to resize the hard drive to keep the machine as one file but
not sure how I would do this.

Ryan
