I'm unable to detach a disk from a Windows guest using the 'virsh detach-disk' command. Even though 'domblklist' shows the disk attached, and on the FIRST iteration, it says the command "completed successfully," 'domblklist will still show the disk attached and subsequent 'detach-disk' commands fail with 'no disk found whose source path or target is ${location}' ~ # vi...

...a snapshot of all disks. Am I using this option incorrectly? In below examples, I'm trying to snapshot only vdb. However even vda is getting snapshotted regardless of diskspec. Is this a known issue?

Hi! I was reading the Wiki about 'Live Disk Backup with Active Blockcommit, https://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit and see that example shown seems to be using two different names for the same file. First showing the current block device in use: $ virsh domblklist vm1 Target Source ------------------------------------------------ vda /export/images/base.qcow2 Then copying the same file for backup: $ cp /export/images/base.img /export/images/copy.img => Is there are reason why the block device first is called 'base.qcow2' and then ...

I take an internal snapshot (VM is 'shutdown' when taking it) of a qcow2 image like this: $ qemu-img snapshot -c sn1 [my_image].qcow2 I see that snapshot when asking for: $ qemu-img info [my_image].qcow but do NOT see it with: $ virsh domblklist [my_domain] is that how it is meant to be?

Hi, When i use "virsh attach-device rhel disk.xml" when the guest is booting,then i can't find the disk in the guest after booting.But i can find it by "virsh domblklist rhel",and when i want to detach it from the guest and use "virsh detach-disk rhel vdb", i still can find the disk by "virsh domblklist rhel" The disk.xml is like: <disk type="file" device="disk"> <driver name='qemu' type='raw'...
