Hi there, We have been experiencing occurrences of user domains hanging. It has happened three times so far this year on the same VM. The last time it occurred I noticed over 200k entries in the /var/log/xen/qemu-xxxxxxxxx.log of the following message : track_dirty_vram(f0000000, 160) failed (-1, 22) When the user domain hangs, you can still connect to the console via VNC but just get a static image. There is no network access to the VM. User domain is running Oracle 9.0.2 on Windows 2003 Enterprise Server R2 with 4 VCPUs and 4 Gb RAM. Domain 0 is running Xen 3.3.0 with Linux 2.6.24-28 on Ubuntu 8.04.4 LTS. Hardware is a Dell PowerEdge R210 with a quad core Xeon X3450 and 8Gb RAM. Can anyone shed any light on this problem?
