Dell PowerEdge 2850 / Xen / Windows 2003 / Debian
Hi, recently I came across a deal on a bunch of Dell PowerEdge 2850 servers
and I was hoping to use them to run Debian with Xen to provided
virtualization support for Windows 2003 and other Debian installations. I
was hoping to install 2 copies of Windows 2003 as well as 2 copies of Debian
all on top of the DOM0 Debian installation.
The servers have dual 3.2ghz CPU''s and include 16GB

guest OS is also a Debian 7 system running a non-SMP kernel. The error

Hi,
I'm running CentOS 5.5 (on ThinkPad x61).
I use KVM to run a SLES 11.0 (32bits, kernel 2.6.27.19-5-pae) guest.
The "cat /proc/cpuinfo" got the result:

lastest xen unstable crash
Hi everyone,
I was trying to build a new machine but the system keeps rebooting.
I used the lasted unstable version from xen-unstable.hg.
I have tried with Fedora 16 (kernel 3.3.0-8) and Xubuntu 11.10 (3.0.0.17-generic).
The output to my serial console is attached.
Cheers,

Hi All,
I have recently installed CentOS 6.3 with QEMU+KVM for Virtualization.
I have successfully created a Windows 2003 VM with 4GB of RAM. The host

the cores is shown below:

Xen shows single processor on a dual core system
Hi all,
On dual core processor machine, I installed ubuntu-8.04 in which I
installed xen-3.2.
In ubuntu:
# cat /proc/cpuinfo --> Shows two processors information.
But in Xen on the same machine:
# cat /proc/cpuinfo --> Shows only one processor information.
Can anyone please explain what could be the reason behind this?
Thanks

Kashyap: I have not tried integrating your guest xml but I will look over
it today when I get a chance. Thank you.

anything else that would be helpful in debugging this. Thank you,

serialization regression in 2.15.0 beta
Hi,
I am experiencing a problem related to serialization behavior in
2.15.0 beta (binary installed from Debian unstable) and 2.16.0 (from
svn) that is not present in 2.14.2 (binary from Debian testing).
I don't fully understand the problem. Also, I tried but have not yet
been able to create a small, self-contained example that reproduces
the problem. However, I do have a large, not

'virsh capabilities' on Debian Wheezy-amd64 reports different cpu to Wheezy-i386 (on same hardware)
Hi
On a range of Dell servers containing Intel 64bit processors, 'virsh
capabilities' reports the cpu differently on Debian Wheezy-amd64 and
Wheezy-i386. The results given by the Wheezy-i386 version seem very
wrong (since n270 is an Atom processor). Apart from architecture, the
package versions of libvirt-bin are identical: 1.2.1-1~bpo70+1.
/usr/share/libvirt/cpu_map.xml files are

2.6.30.1 dom0 Xen patches
I''ve been trying for several days to get a xen dom0 booting as
described on Boris Derzhavets blog.
I have been able to boot Jeremy Fitzhardinge''s pv_ops kernel under
xen, but my X server wouldn''t start so I''ve been trying to get Andrew
Lyon''s rebased opensuse patches to work.
I have asked for help in the freenode ##xen channel but they
