Re: My domU cpuinfo shows "cache seize: 16KB" ater upgrading to Xen-3.3.0... but in Xen-3.2 it has 2048KB!
No one knows about this?!
It''s normal for domU in Xen-3.3 to have only 16KB of CPU cache size?
Thanks!

libvirt does not show same CPU Model as /proc/cpuinfo for CPU Model info.
Hi ,
Created new thread .
Environment:
Bare Metal server + CentOs with qemu/KVM +libvirt for virtualization
Guest Instantiated with virt-install with forced CPU model like below

can anyone confirm this is doable with these two boxes, and if so
which should be masked to which ??

Check if VT is enabled
Hello group,
I recently purchased an HP m7360n computer which has an Intel Pentium D 920
processor in it. Unfortunately there is no BIOS option to enable or disable
VT. The board it sits on uses the Intel 945P chipset.
If I am in linux and do a ''cat /proc/cpuinfo'' I get this:
[root@localhost ia32]# cat /proc/cpuinfo
processor : 0

Xen 3.3.0 cpu cache problems
Dear Xen users,
I have a problem with "Xen 3.3.0". All domU (paravirt) only have "32 KB"
of cache instead of "6144 KB" as listed in dom0. This is really
noticeable under load since the system tends to be really slow.
I did not have this problem with "Xen 3.2.1".
I''m using the same domU configuration files for the new and the old
installation.

Windows 2008 x64 crashes on install
Hello,
I am trying to install Win2008 x64 on xen. However it always crashes
with: 0x0000005b which from my research means incompatible CPU. Can
anyone assist with this? How can I get x64 to work?

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

CPU model and missing AES-NI extension
Hi,
today I tried to configure a guest using Virt-Manager and used the "copy
host cpu configuration" option which resultet in a "Sandy Bridge" model.
What I noticed is that for example the "aes" extension is not available
in the guest even though it is available on the host cpu.
This is what the host cpu looks like:

Host does not support virtualization type 'xen'
Hello Community,
I successfully installed and run xen (xm list and xm info can output
appropriately).
However, while I was installing domU image by using virt-install -p at
domU OS. I encountered an
error information" Host does not support virtualization type ''xen'' ".
I built xen from source. Some of my friends have the same issue, but if
they use pre-build xen, the

qemu VS tapdisk2 VS blkback benchmarks
Hi all,
as promised I run some simple benchmarks using tapdisk2 and the new qemu
as disk backends.
If you are in a hurry skip to the last section to see the test results.
SOFTWARE REQUIREMENTS
---------------------
In order to reproduce these results you need to use the new qemu with
linux aio and O_DIRECT as disk backend:
- apply the libxl patches that Anthony sent to the list a little while

More than doubling performance with snow
Hey my R buddies,
I installed the "snow" and "rpvm" package on my Lenovo Thinkpad T400
today. The experiment below gave me a surprise. The time consumed by
serial processing was several times larger than that taken by parallel
processing. I'm very curious how this happened. Thank you very much.
