The file exists now:

I had to add the directories channel and target. VM is starting fine,
snapshot is possible.
But still some slight problems:
virsh # snapshot-create-as --domain sles11 --name sn_sles11 --atomic
--disk-only --live --quiesce
error: Operation not supported: live snapshot creation is supported only
with external checkpoints
I thought --disk-only would create external snapshots ?
virsh # snapshot-create-as --domain sles11 --name sn_sles11 --atomic
--disk-only --live --quiesce --diskspec vdb,snapshot=external
error: Operation not supported: live snapshot creation is supported only
with external checkpoints
Hm. Specifying external explicitely also does not help.
virsh # snapshot-create-as --domain sles11 --name sn_sles11 --atomic
--disk-only --quiesce --diskspec
vdb,snapshot=external,file=/var/lib/kvm/images/sles11/sn_disk0.qcow2
Domain snapshot sn_sles11 created
Omitting --live is the key. But I thought I need it because i'm
snapshotting a running vm ?

I still have 1.2.5.
I tried to blockcommit:
virsh # blockcommit sles11 vdb --path
/var/lib/kvm/images/sles11/sn_disk0.qcow2 --wait --verbose --delete
error: option --path already seen
what does that mean ?
virsh # blockcommit sles11 --path
/var/lib/kvm/images/sles11/sn_disk0.qcow2 --wait --verbose --delete
error: unsupported flags (0x2) in function qemuDomainBlockCommit
virsh # blockcommit sles11 --path
/var/lib/kvm/images/sles11/sn_disk0.qcow2 --wait --verbose
error: Operation not supported: committing the active layer not supported
yet
Ok. Omitting --delete removes one error, but now I have another one. What
means "not supported yet" ? Does that mean I have a software which offers
blockcommit in the help,
but it is not completely implemented ?
virsh # blockcommit sles11 --path /var/lib/kvm/images/sles11/sn_disk0.raw
--wait --verbose
error: invalid argument: No device found for specified path
Which path do I have to provide ? The one to the base or the one to the
snapshot ? I tried both, but not working.
Do I have all these problems because I'm using 1.2.5 ? That's the official
version of libvirt which is included by SuSE for SLES 11 SP4. But it's
lacking functionality which is offered in the help ?
Oh my god.
