Re: [libvirt-users] VM with transient disk



Hi Osier,

are there other hypervisors supporting it?

And what about qemu's option "snapshot=on" ?

Best, Till

I want to use transient disks with libvirt.
According to [1], the transient disk feature has been supported since
0.9.5.
Hence, I have installed libvirt 0.9.6 for Ubuntu Lucid from [2] and
used the following disk configuration:

<disk type='file' device='disk'>
<driver name='qemu' type='raw'/>
<source file='/home/till/test.img'/>
<target dev='vda' bus='virtio'/>
<transient/>
</disk>

However, I get:
unsupported configuration: transient disks not supported yet

That's because libvirt supported it yet, but qemu still haven't
complete the support. Not sure if the newest upstream
qemu already supported it though.
