Re: [Xen-users] Problem with installing/running domU OS on HVM machine

[Simon Gao <gao@xxxxxxxxxxxxxxx>]

The machine has Athlon 64 dual core CPU and uses AM2 socket. HVM is
supported based on "xm dmesg":

....
(XEN) Detected 2004.225 MHz processor.
(XEN) CPU0: AMD Flush Filter disabled
(XEN) CPU: L1 I Cache: 64K (64 bytes/line), D cache 64K (64 bytes/line)
(XEN) CPU: L2 Cache: 512K (64 bytes/line)
(XEN) CPU 0(2) -> Core 0
(XEN) AMD SVM Extension is enabled for cpu 0.
(XEN) Intel machine check architecture supported.

(XEN) AMD: Disabling C1 Clock Ramping Node #0
(XEN) AMD SVM Extension is enabled for cpu 1.

Based on postings I've read so far, hvmloader must be compiled for
32bit. However, it does not work if I copied the file from a 32bit
CentOS machine and use on the Athlon 64 machine.
