help--dom0 network goes unpingable when xend starts
I installed 64-bit xen 3.1.0 (from xensource.com tarballs) on
three new machines today, using a configuration setup that I''ve
used successfully many times before. However, I encountered a
new problem.
These are Dell Poweredge 1950 servers, by the way.

installing DomU with two network bridges via virt-install
I have a Xen DomU configuration that was made in the days before
libvirt and virt-install. In this configuration
I have:
vif = [ ''mac=00:16:3e:05:06:01, bridge=xenbr0'', ''mac=00:16:3e:05:06:0a,
bridge=xenbr1'' ]
and then in xend-config.sxp I define

where my-network-bridge is in the scripts directory and looks like this:

changing behavior of xendomains stop
I''m running xen 3.1.2 as bastardized by RedHat on a redhat
clone operating system. I''m using the xendomains script
as it came out of the box to start my domU''s at boot
and stop them at shutdown.
There are three problems right now:

Nasty kernel panic
I have seen the following kernel panic 5 times today on
three different machines, two of which had been stable
for months and one of which is a brand new install.
We are running the x86_64 xen kernel and userland tools that came in the
Xen 3.1.0
tarball from xen.org, on top of scientific linux (redhat clone)
5.1 or 5.2.

RHEL6 beta vs. Xen
Has anyone yet figured out what it would take to make Xen
run on top of the Red Hat Enterprise Linux 6 beta?
We are heavily invested in Xen under RHEL5 (actually
a redhat clone) distribution, but already the xen kernel
they are shipping with update 4 and 5 is shaky and has bugs
which they don''t seem to be in a hurry to fix.
Basically I am wondering if Redhat 6 is just going to

making new initrd, how to do it?
I have installed the xen 3.1.0 x86_64 tarball
compiled for RHEL5 on a RHEL5 system. The system in question
was able to boot with the xen kernel that came with RHEL5.
I untarred the tarball, and did
cd /boot
mkinitrd /boot/initrd-2.6.18-xen.img 2.6.18-xen
The command exited properly and made a initrd image.
The machine booted with a grub.conf entry like this:

are Xen 3.1.0 kernels CVE-2007-4573 vulnerable
Does anyone know if the Xen 3.1.0 kernels as distributed in
the "open source" tarballs (x86_64 version) are vulnerable to the
recently-announced vulnerability CVE-2007-4573?
IF so, is there any plan to release patched tarballs anytime soon?
Thanks

guest os time drift wild
HI, guys
Recently,I met a problem.
Xen''s version: 3.4.3
guest os:redhat 4.8 32bit
And xen.independent_wallclock = 1 has been set.
The time of guest os change to be fast suddenly, about 2000 second.
because the change is too wild, ntp didn''t sync to the ntp server''s time.
my application is dependent on the systme time. And this occurs a lot of times.

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

Linux distributions supported by Xen as PVM domUs
Hi:
Reading Red Hat''s Website and a printed manual of RH184 (Red Hat
Virtualization course) I see that RHEL 5 only supports RHEL 4.5 and
RHEL 5 as paravirtualized guests. So I asume this is the same
situation for CentOS 5, right?
What''s the dependency between Xen versions for paravirtualized guests?
I ask this questions because I got this experiences:

Changes to 'ADJCALLSTACK*' and 'callseq_*' between LLVM v4.0 and v5.0
Hi LLVM-Devs,
I have managed to complete updating our sources from LLVM v4.0 to v5.0, but
I am getting selection errors for 'callseq_end'. I am aware that the
'ADJCALLSTACKUP' and 'ADJCALLSTACKDOWN' patterns have changed, and have
added an additional argument to the TD descriptions for these.
There are interactions with 'ISD::CALL' and 'ISD::RET_FLAG',

Changes to 'ADJCALLSTACK*' and 'callseq_*' between LLVM v4.0 and v5.0
Hi Martin,
Pseudo CALLSEQ_START was changed in r302527, commit message contains
details on the changes.
However CALLSEQ_END was not modified. If your made changes to
ADJCALLSTACKUP to add
additional argument, that may result in error.
Thanks,

Changes to 'ADJCALLSTACK*' and 'callseq_*' between LLVM v4.0 and v5.0
Hi Serge,
Thanks for your help. I have looked at the change log, and so far as I can tell, my implementation is pretty much identical to all of the in-tree targets, but I’m missing something and can’t see what it is. I have simplified my TD description to just:

FW: Random Mac addresses on Dom0
When I boot from a regular centos kernel, I get this for a mac
00:19:db:e5:91:4f somehow it is getting reversed. Could I have messed
something up when I built the kernel?

Problem when running 32 on 64
Hi,
I have been able to run 32 bit virtual machines on a 64 bit machine
quite nicely with xen3.1 but sometimes when running yum the messages
"do_wp_page: bogus page at address 0070d638" and "kernel: VM: killing
process yum" and yum just stops working. I also get Kernel Panic.
Does anyone have any idea, what could be the probem?
Thanks,
Ricardo
