Re: [libvirt-users] some problem with snapshot by libvirt

to create snapshot ,I did step below: virsh snapshot-create-as centos snap1 --disk-only --atomic --no-metadata virsh snapshot-create-as centos snap2 --disk-only ...... ........................ virsh snapshot-creates-as centos snap10 ..... then i got 10 snapshot of a vm, to revert, i just did the follow step: 1 destroy centos 2 editor="sed -i 's/centosdisk.snap10/centosdisk.snap1/g'" virsh edit centos 3 rm -f centos.snap{2,3,4,5,6.....} 4 start centos is these steps correct? and another question is ,when i revert to a snapshot,some files of the vm's system missing，does this have any relation with the disk cache mode (writeback,writethrough,none,etc.)???how could i avoid that happen?? thanks.
