Hi and hello, I have a problem confusing me. I hope someone can help me with it. I followed a "best practise" - I think - using dedicated zfs filesystems for my virtual machines. Commands (for completion): [i]zfs create rpool/vms[/i] [i]zfs create rpool/vms/vm1[/i] [i] zfs create -V 10G rpool/vms/vm1/vm1-dsk[/i] This command creates the file system [i]/rpool/vms/vm1/vm1-dsk[/i] and the according [i]/dev/zvol/dsk/rpool/vms/vm1/vm1-dsk[/i]. If I delete a VM i set up using this filesystem via[i] virsh undefine vm1[/i] the [i]/rpool/vms/vm1/vm1-dsk[/i] gets...

Use PM_FREEZE, PM_THAW and PM_RESTORE power events for suspend/resume/checkpoint functionality, instead of PM_SUSPEND and PM_RESUME. Use of these pm events fixes the Xen Guest hangup when taking checkpoints. When a suspend event is cancelled (while taking checkpoints once/continuously), we use PM_THAW instead of PM_RESUME. PM_RESTORE is used when suspend is not cancelled. See

destroy() is being called on exception in both start() and create(). It needs to be called only in create().

...ou can specify --wait instead of --pivot for 'virsh blockcommit' and it will finish after step 2 above. Also one of the cases which would help is that libvirt could actually remove the file after commit, which would avoid the original problem, since the file would still be there. > oot@vm1 ~]# virsh blockjob serv1r2 vda > Active Block Commit: [100 %] > > [root@vm1 ~]# virsh blockjob --pivot serv1r2 vda > > [root@vm1 ~]# > [root@vm1 ~]# ls -l /var/lib/libvirt/images/serv1r2.qcow2 > -rw-r--r--. 1 qemu qemu 54200696832 Jun 30 10:39 /var/lib/libvirt/images/serv1r...

...ions are covered informally throughout the text, this is not a VIRTIO specification change proposal. The VM-to-VM capable virtio-net PCI adapter has an additional MMIO BAR called the Shared Buffers BAR. The Shared Buffers BAR is a shared memory region on the host so that the virtio-net devices in VM1 and VM2 both access the same region of memory. The vring is still allocated in guest RAM as usual but data buffers must be located in the Shared Buffers BAR in order to take advantage of zero-copy. When VM1 places a packet into the tx queue and the buffers are located in the Shared Buffers BAR, t...

...ne volume group spans the physical disk. then, various logical volumes are created for the host and (Linux) guest OSes. this makes it easy to resize logical volumes should it be needed. is a setup like this possible with libvirt? the best i can think up, so far, is to create a new logical disk, vm1, and pass that as an argument to the -f option of virt-install. then, during the installation i can setup LVM within the guest. not sure if this would even work if i need to expand the volume size. first i would expand the size of vm1. then, within the vm1 OS i would expand the size of the root...
