From PrgmrWiki

This page is for listing issues with xen in various distros running on prgmr.

  • Ubuntu general xen info
  • Debian general xen info
    • Restoring a saved domU (like when a dom0 reboots) with the 2.6.26 old style xen support kernels in the Debian lenny release triggers the "time went backwards" error, filling up dmesg and causing high load.
    • The 2.6.26-2-xen-686 kernel doesn't boot with >1023M memory, and has the old style xen support. The 2.6.26-2-686-bigmem kernel with pae support also has xen support from pvops instead of the old style, and works well with >1023M and saving/restoring. Install the linux-image-2.6-686-bigmem package instead of linux-image-2.6-xen-686. The generic 2.6.32 kernels in squeeze all support pvops as a domU.
    • The 2.6.26-1-xen-amd64 kernel gets "blocked for more than 120 seconds" on various processes mysteriously and upgrading to a pvops (2.6.32) amd64 kernel could help. Debian bug 516374 may be related.
