Hi all, on a fully patched CentOS 7.4 x86-64, I see the following behavior: - when creating a new volumes using vol-create-as, the resulting file is a qcow2 version 2 (compat=0.10) file. Example: [root@gdanti-lenovo vmimages]# virsh vol-create-as default zzz.qcow2 8589934592 --format=qcow2 --backing-vol /mnt/vmimages/centos6.img Vol zzz.qcow2 created [root@gdanti-lenovo vmimages]# file zzz.qcow2 zzz.qcow2: QEMU QCOW Image (v2), has backing file (path /mnt/vmimages/centos6.img), 8589934592 bytes [root@gdanti-lenovo vm...

Hi,guys I wanna to get the disk snapshot size, but found nothing libvirt commands related,except qemu-img. I create two disk snapshots, but nothing return its' size [root@cskvm01 qcow2]# qemu-img info /mnt/e6758700-af68-3c06-ade3-53f5f9b93507/e2cf6551-0d2c-4382-a86c-8ba633954ff2 image: /mnt/e6758700-af68-3c06-ade3-53f5f9b93507/e2cf6551-0d2c-4382-a86c-8ba633954ff2 file format: qcow2 virtual

I have a system with two CentOS 7.1 guests. When I created the VMs I did not have enough storage space in the default location /var/lib/libvirt/images so I moved the default location to a directory /home/vmimages. While this configuration is functional I regret creating a new storage pool in /home. I would like to create a separate partition to place the VM images removing them from their present /home/images location. The /home partition is presently empty other than the VM images directory so I can ea...

Hi Folks, I find myself trying to expand a 2-node high-availability cluster from to a 4-node cluster. I'm running Xen virtualization, and currently using DRBD to mirror data, and pacemaker to failover cleanly. The thing is, I'm trying to add 2 nodes to the cluster, and DRBD doesn't scale. Also, as a function of rackspace limits, and the hardware at hand, I can't separate
