Hi, the below three internal snapshots were taken when the guest is running 'live'. Any hints on why the time to take snapshots keep increasing ? If you notice, the 2nd and 3rd internal snaphtots took more than 4 minutes each (note: there is no noticeable content change from snap1 ) #==================================================# [root@localhost vmimages]# time virsh snapshot-create-as f17vm3-with-b snap1 snap1-f17vm3-desc Domain snapshot snap1 created real 0m57.734s user 0m0.009s sys 0m0.024s [root@localhost vmimages]# [root@localhost vmimages]# virsh snapshot-list f17vm3-with-b Name Creation Time State ------------------------------------------------------------ snap1 2012-10-04 06:55:38 -0400 running [root@localhost vmimages]# #==================================================# [root@localhost vmimages]# time virsh snapshot-create-as f17vm3-with-b snap2 snap2-f17vm3-desc Domain snapshot snap2 created real 4m19.126s user 0m0.020s sys 0m0.030s [root@localhost vmimages]# #==================================================# [root@localhost vmimages]# time virsh snapshot-create-as f17vm3-with-b snap3 snap3-f17vm3-desc Domain snapshot snap3 created real 4m45.053s user 0m0.013s sys 0m0.032s [root@localhost vmimages]# #==================================================# [root@localhost qemu]# qemu-img info /home/kashyap/vmimages/f17vm3-with-b.qcow2 image: /home/kashyap/vmimages/f17vm3-with-b.qcow2 file format: qcow2 virtual size: 5.0G (5368709120 bytes) disk size: 755M cluster_size: 65536 backing file: /home/kashyap/vmimages/base-f17.qcow2 Snapshot list: ID TAG VM SIZE DATE VM CLOCK 1 snap1 232M 2012-10-04 06:55:38 19:58:19.804 2 snap2 247M 2012-10-04 07:03:09 20:04:53.360 3 snap3 244M 2012-10-04 07:08:23 20:05:48.889 4 snap4 0 2012-10-04 08:51:16 00:00:00.000 5 snap5 0 2012-10-04 08:53:04 00:00:00.000 [root@localhost qemu]# #==================================================# [root@localhost qemu]# virsh snapshot-list f17vm3-with-b Name Creation Time State ------------------------------------------------------------ snap1 2012-10-04 06:55:38 -0400 running snap2 2012-10-04 07:03:08 -0400 running snap3 2012-10-04 07:08:23 -0400 running snap4 2012-10-04 08:51:16 -0400 shutoff snap5 2012-10-04 08:53:04 -0400 shutoff [root@localhost qemu]# #==================================================# -- /kashyap -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
