[rhos-list] Problem creating an instance using nova boot

Tue Sep 4 01:26:50 UTC 2012

I was able to replicate this Essex issue today using a rhel 6.3 x86_64 guest within Oracle VirtualBox v4.1.20 running on a Windows 7 host on a PC with an Intel i3 processor. Both the PC bios and virtualbox guest had processor virtualization enabled.

To build the Essex single VM, I followed the Red_Hat_OpenStack_Preview-1-Getting_Started_Guide-en-US.pdf completely except for one "extra" command. After completing the commands on page 20 and getting this:

[root@ rhel63-test1 ~]$ for srv in api cert network objectstore scheduler volume compute ; do \
> sudo service openstack-nova-$srv start ; \
> done
Starting openstack-nova-api:                               [  OK  ]
Starting openstack-nova-cert:                              [  OK  ]
Starting openstack-nova-network:                           [  OK  ]
Starting openstack-nova-objectstore:                       [  OK  ]
Starting openstack-nova-scheduler:                         [  OK  ]
Starting openstack-nova-volume:                            [  OK  ]
Starting openstack-nova-compute:                           [  OK  ]
[root@ rhel63-test1 ~]$ [root@ rhel63-test1 ~]$ grep -i ERROR /var/log/nova/*
/var/log/nova/compute.log:2012-09-03 17:38:26 CRITICAL nova [-] internal error Cannot find suitable emulator for x86_64
[root@ rhel63-test1 ~]$

I then ran only one of commands suggest from the webpage http://fedoraproject.org/wiki/Getting_started_with_OpenStack_EPEL#Installing_within_a_VM as shown below:

[root at rhel63-test1 libexec]# ln -s /usr/libexec/qemu-kvm /usr/bin/qemu-system-x86_64
[root@ rhel63-test1 ~]$ for srv in api cert network objectstore scheduler volume compute ; do \
> sudo service openstack-nova-$srv stop ; \
> done
[root@ rhel63-test1 ~]$ for srv in api cert network objectstore scheduler volume compute ; do \
> sudo service openstack-nova-$srv start ; \
> done

No more error in the logs!!!!! Hope this helps you Regis.

Hello,

I set my all SELinux to permissive mode and still nova-compute doesn't start happily.

compute.log

CRITICAL nova [-] internal error Cannot find suitable emulator for
x86_64

I also checked the installed qemu-kvm package and it's:
qemu-kvm-0.12.1.2-2.295

Did someone manage to setup and run OpenStack Essex Preview on a VM with RHEL 6.3?

Thanks.
Regards.
Regis
