Hello,
I am using Citrix XenServer for my VM environment. I found that If I am using samba 3.4.3 and dump a vm from a Citrix xen node the resulting image is not importable(ie corrupt) into xenCenter. If I am using samba-3.3.9 and perform the same operation everything works great. To dump the vm's from Xen I mount a samba share from the domU OS. I use the following xen commands to dump the vm

mount -t cifs //172.27.1.100/xenBackups /mnt -o username=sdrinkwater,pass=somepass,dom=ad.pa-ucl.com
xe vm-snapshot vm=guest_name new-name-label=backup_vm
xe template-param-set is-a-template=false uuid=snapshotUUID
xe vm-export vm=snapshotUUID filename=exportfilename.xva
xe vm-uninstall uuid=snapshotUUID force=true
umount /mnt

Has anyone else experienced this ?? My info is as follows

XenServer mount.cifs version --> mount.cifs version: 1.10
My two test samba servers where build from source with the following config
../configure --with-winbind --with-pam --with-aio-support
