Re: [Xen-users] Dom0 crash on hvm creation

[Steven Timm <timm@xxxxxxxx>]

Did centos 5.1 do something different than the Red Hat on which
they were based?  the Red Hat 5 /update 1 is still claiming to
have xen 3.0.3 and 32-bit guests on 64bit dom0 as a "technology preview",
i.e. it doesn't work yet,.  If anyone does have that feature working
on either redhat or centos, let me know.
