Re: [Xen-devel] a ton of kernel issues

[George Shuklin <george.shuklin@xxxxxxxxx>]

Use suse and Centos5 (not 6) kernels. They works right with xen better 
then others. OpenSUSE release pretty offten, so they have at least 
2.6.34, 2.6.37 and 3.1. Or you can use old centos 2.6.18.
All those kernels is '-xen', not vanilla. pv_ops is still have some 
issues with memory limits, but any new kernel (3.0+) will boot normal 
and operates with very minor glitches. Older pv_ops (f.e. debian 2.6.32) 
have some more major issues.
