I've been trying to implement the quota system for a Linux cluster. I'm trying it out on a mini-cluster of 4 CentOS 6.3 VMs. I've named them: lion-login lion-sn1 lion-cn01 lion-cn02 All nodes are on the virtual subnet 192.168.56.0/24. lion-sn1 (storage node 1) is the NFS server and the other three nodes are the NFS clients. /etc/exports on lion-sn1: /home 192.168.56.0/24(rw) /etc/fstab on the other nodes: lion-sn1:/home /home nfs defaults,usrq...

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

Hi Looking in to implementing (CBT like) delta backup for KVM. The following looks promising..(last paragraph) http://wiki.qemu.org/Features/Snapshots2 * In the last para, there is a mention of copy the blocks from the disk using dirty-bitmap as reference. How to accomplish this ? block-mirror with bitmap or is there a qemu-img command ? some details would be

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?
