our guests with any reason, the ping dont response. I solve this issue, I

I am running xen 3.2-1 (Debian 3.2.1-2) on Debian Lenny

domUs don't know their `eth0' anymore
Hello!
I recently upgraded a number of Debian testing packages (three days ago)
and just now rebooted the system, with the effect that the Xen domUs
don't know their `eth0' devices anymore:
#v+
# ifconfig eth0
eth0: error fetching interface information: Device not found

Running Fedora 10 (and rawhide) Xen guests/domUs on CentOS 5 dom0
Hi list!
Now when Fedora 10 is out, I thought of writing here what's needed to
run Fedora 10 Xen domUs on CentOS 5 dom0.
Fedora 10 does not have separate kernel-xen, but instead Xen domU
support is included in the normal kernel-PAE.i686 and kernel.x86_64
(based on the pv_ops Xen support included in the mainline/vanilla Linux kernels).
RHEL 5.3 beta (and final obviously too) includes

my domUs have a slow network rate for outside networks.
Hi,
I have some network problems with my DomUs (etch) on a debian etch
running xen 3.0.3. The domain0 is a DL360 G5 with tg3 network card
If i download something from outside my dom0 box to a domU, i get this
network rate: ~865kbits ... and it must be ~ 10Mbits, i think.
Doing some tests with iperf i get this:
[ 4] local outside_server port 5001 connected with _domU_ port 54889

domUs dropping off the network (Xen 3.0.2)
Hello,
We''ve recently started seeing several domUs on multiple machines losing
all network connectivity. At least one of these machines (since they are
customer machines I can''t verify it for all of them) give the error:

Bug#409355: xen-utils-common: please make width of hostname column in xentop wider
Package: xen-utils-common
Version: 3.0.3-0-2
Severity: wishlist
Tags: patch
Currently when hostnames are wider than 10 chars, the xentop output is messed up.
Please add the following patch to support up to 20 chars, or better yet, allow the
columns to auto size :)

Gathering "metal" stats
Hey All,
I’m attempting to gather stats on usage of the “metal”, by which I mean the
physical host’s hardware. I would like to know the CPU, IO, and network
stats for the hardware.
Normally I would get these from /proc/stat, /proc/diskstat, and ifconfig
respectively. However, because of the segregation of VMs and Dom0’s special
relationship as a paravirtualized I don’t know if I can trust this

RE: [CentOS] Running CentOS 4.6 domUs on CentOS5.1 dom0 and domUscrash
Sorry for the top post, blackberry.
Well I like to be able to install my machines in the xenstore with 'xm new'
and then manage them from there, but virt-install and virsh are useful
too, so I just use CentOS base then replace their xen with the one from
xen.org keeping libvirt and now I have the best of both worlds.
The commercial one isn't without gripes too. Like I wish they had

Jumbo frames with domUs in bridging mode
Hi everyone,
I have looked through the list archives and seen a few posts about jumbo
frame support, but there is no definitive answer on whether or not it
has been tested or is working for anyone. I tried using an MTU of 9000
in a domU and encountered some very interesting and not-so-great
results. My machines used in this test are:
* NFS (physical)
* dom0 (physical)
* domU (virtual)

Error: Device 0 not connected
Hi,
I''m new to Xen and I''ve set up a few domUs using Debian (I suspect
there may be a problem there, see at end).
To begin with everything worked OK, I rebooted domUs without any
problems, but twice now when I try when I try to restart or shutdown a
domain, the xm command locks up.

Bug#744927: No VIF information in xentop with xl
Package: xen-utils-4.3
Version: 4.3.0-3+b1
Using the xl toolstack there's no information about the networks of the
domUs in xentop. I have a PV and a HVM domU and both are shown as having 0
network interfaces, while in fact they have functioning interfaces.
Here's one of the interfaces that should be shown, from xenstore:

domUs Clock synchronisation
Hi everybody!
I know this is an ultraknown issue, but in my case i think
it is going beyond.
As you may guess my domUs clocks go faster or slower
They come with the same OS (Centos 5 2.6.18-92.1.18.el5 ) but each of them
have a different clock speed.
Why? Dom0 does not syncronize domUs :
So i watched out looking for any solution....
First attempt:
/proc/sys/xen/independent_wallclock = 0

Migrated domUs hangs
Hello,
I have a live migration problem on my setup. Migrated DomUs hang, but
continue as normal when migrated back.
Both nodes are i386 Debian Squeeze dom0 (xen 4.0.1 + pvops0
2.6.32-5-xen-686)
Node A is a 32bits 2.4 Ghz Pentium4, node B is a 32bits 2.0 Ghz Celeron.
DomUs are Debian Squeeze (2.6.32-5-xen-686 >= 2.6.32-22 or
2.6.32-5-686-bigmem >= 2.6.32-22) and Ubuntu Maverick

time synchronization of dom0 and domUs still not working?
Hi folks,
I am using Xen 2.0.7 with debian based dom0 and domUs on several
machines. Every few days I find the clocks of dom0 and domUs on the same
machine to differ between seconds and hours.
I know this is mentionened every now and then on the list. What I want
to know: Is this bug still officially not fixed? Is something done to
fix it or is it left as is?
I just have to know the state

drifting clock in domUs
Hello,
On a xenserver with several (39) domUs, we experience problems with the
system clock of the domUs. The clock seems to drift away several seconds
up to two minutes from the dom0 clock.
We do have set independent_wallclock=0. According to the docs (i.e.
http://wiki.xensource.com/xenwiki/InstallationNotes) that way domUs
should use the dom0 clock, but apparently that''s not the case.

Cannot start xen domUs anymore, domUs hang on kernel startup, happens after a long dom0 uptime
Hello!
I've noticed this problem two times now.. last time I fixed it by rebooting
the (centos 5.1 x86 32b) xen host/dom0.
Symptoms:
- Already running domUs (debian 2.6.18-6-xen-686 32b PAE) continue running
and working OK
- Cannot start new domUs (debian 2.6.18-6-xen-686).. kernel bootup just
hangs before running initrd. Same domU with the exact same xen domU cfgfile worked
earlier.

Xen 4.1 auto shutting down of DomUs at reboot
Hi,
Im just setting up a new server which I have nearly complete.
I have the DomUs automatically starting by placing the sym links in
/etc/xen/auto and by executing /etc/init.d/xendomains on startup however
I cannot get them to shutdown gracefully.
I have set in /etc/default/xendomains to shutdown and not save but it
seems this setting is ignored and the DomUs just get killed. Is
