Hi everyone!
I use the libvirt(version: 1.2.2) and QEMU(version: 2.2.1) to test qemu snapshot
features:
I tried virsh blockcommit when VM offline, the virsh blockcommit failed: the error
messase as below:
error: Requested operation is not valid: domain is not running
when I start the VM, the virsh blockcommit work fine!
my question is : we need virsh support blockcommit when VM offline。how do?
we test qemu snapshot as follows:
we need create snapshot of the cycle,and by virsh blockcommit merge snapshot
chain,but whenVM offline, the virsh blockcommit will fail, someone suggest me:when VM
offline,may use qemu-img commit to submit snapshot turn,but qemu-img can't modify
snapshot chain backing relation,it need we use qemu-img rebase amend snapshot‘s
backingfile, the main question is when we use qemu-img rebase modify snapshot's
backingfile, if someone start the VM, it will may lead to VM filesystem readonly。
we shoule solve the question? thanks!
