[CentOS-virt] Xen PV domU reported as Xen-HVM

[Karl Johnson]

Hello,

I am running two dom0s, one on CentOS 5 with Xen 4.1.2 (from Gitco) and the
other one on CentOS 6 with Xen 4.2.4 (from Xen4CentOS). I host one LVM
based domU on both from the same template (CentOS 6 PV) with the same Xen
config (see below). However, the domU on Xen 4.1 reports itself as Xen PV
while the domU on Xen4CentOS reports itself as Xen HVM.


== First domU ==

virt-what and cPanel scripts report domU as: xenpv

dom0: 2.6.18-371.6.1.el5xen Xen 4.1.2

domU Config:

bootloader = '/usr/bin/pygrub'
extra      = ''
memory     = 6144
hostname   = 'web2.x.ca'
cpu_weight = 256
name       = 'vm115'
vif        = ['ip=205.X.X.X, vifname=vifvm115.0, mac=00:16:3e:7a:X:X']
vnc        = 0
vcpus      = 6
vncviewer  = 0
serial     = 'pty'
disk       = ['phy:/dev/xen/vm115_img,xvda1,w',
'phy:/dev/xen/vm115_swap,xvda2,w']

domU kernel: 2.6.32-431.5.1.el6.x86_64

root at web2 [~]# virt-what
xen
root at web2 [~]#



== Second domU ==

virt-what and cPanel scripts report domU as: xenhvm

dom0: 3.10.32-11.el6.centos.alt.x86_64  Xen 4.2.4-29.el6

domU Config:

bootloader = '/usr/bin/pygrub'
extra      = ''
memory     = 6144
hostname   = 'web3.x.ca'
cpu_weight = 256
name       = 'vm116'
vif        = ['ip=205.X.X.X, vifname=vifvm116.0, mac=00:16:3e:cf:X:X']
vnc        = 0
vcpus      = 6
vncviewer  = 0
serial     = 'pty'
disk       = ['phy:/dev/xen/vm116_img,xvda1,w',
'phy:/dev/xen/vm116_swap,xvda2,w']

domU kernel: 2.6.32-431.5.1.el6.x86_64

root at web3 [~]# virt-what
xen
xen-hvm
root at web3 [~]#

Any idea why?

Kinds regards,

Karl
