Hi! I have Xen (fedora 7 with xen 3.1.0) running with 2 guests (both fedora 7). At night I save both guest and mount their partitions to do a backup. Then I restore the saved machines. Everything appears to be working fine, but I had some problems with restore this weekend. When I arrived to work, one of the guest was not running properly. I tried to shutdown the machine and start it again, but got the following error when trying to start: virsh # start virtual_machine_name libvir: Xen Daemon error : POST operation failed: (xend.err "''uname''") error: Failed to start domain virtual_machine_name Seeking for any problem in log files I found some errors: [2007-09-07 09:14:16 2285] CRITICAL (SrvDaemon:231) Xend died due to signal 11! Restarting it. : : [2007-09-07 09:14:18 2557] DEBUG (XendDomainInfo:1463) XendDomainInfo.constructDomain [2007-09-07 09:14:18 2557] DEBUG (balloon:113) Balloon: 64248 KiB free; need 2048; done.

What can be done so that those errors do not occur any more? Thanks in advance, -- Augusto Castelan Carlson
