Hi
I'm quite new to KVM/libvirt0 so hope you can help
I'm using Ubuntu Lucid 10.04 and libvirt0 0.8.1
When I try a :-
snapshot create vm_name
I get an error, ie 'error -5 while writing'
Googling doesnt bring anything up. Taking snapshots of a vm when it
isnt running works fine.
Can I really only create snapshots of a vm when it isnt running ?
No, you should be able to take a snapshot both while it is running and
while it is off. However, they use different mechanisms so there could be
a bug in the online version. What version of qemu/kvm are you running?
Also, do you have apparmor enabled/running? If so, and if the apparmor policy
hasn't been updated, that might be the source of your problems.
