Re: [libvirt-users] Can I update libvirt while KVM guest os are running
Answer to myself.
Troubleshooted the symptom with my colleague and found the root cause.
In case of libvirt update from 0.6.3 to 0.8.2,
I had to restart my Guest OS.
Otherwise I got an error when I execute attached-disk with libvirt 0.8.2.
error: Failed to attach disk
error: internal error missing disk device alias name for hdc
It was because virDomainDeviceInfo info in struct _virDomainDiskDef
was NOT exist in 0.6.3.
After update, libvirt 0.8.2 does origdisk->info.alias, and it causes this
error message.
I believe there are many changes between 2 versions.
So I conclude that it is safe to stop Guest OS when libvirtd is updated.
Thanks
