Open Stack

Hi Razique,

I executed the start command on the compute node using the domain name option. I got an error message saying that
Error:"Failed to start domain instance-UUID"
Error: Unable to precreate char dev file '/var/lib/nova/instances/ instance-UUID/console.log: No such file or directory.

Can I get help to get rid of this problem?

Thanks,
Krishnaprasad

You have many solutions for that
first try to power it on via
$ virsh start
and check /var/log/libvritd.log

you can use kpartx to discover the partitions within the images, and use the different builtin system tools to fix the partitions
fsck.ext4/ xfs_adm, etc...

Hallo all,

I looked in to forums about recovering VMs in OpenStack ESSEX.  In the dashboard, I could see that the VMs status is "Hard rebooting" with power state Shutoff.  In virsh, I could see that the state is Shutoff. The complete process is taking longer time to finish and I assume it is in a unrecoverable state. Can anybody help me in recovering the data on the VM and the VM itself?

Thanks,
Krishnaprasad
