How is network bridging for Xen handled in F7?
by Christian Reiter
Hi!
Can anybody tell me where i can find docs about handling network bridges for xen domUs in Fedora 7?
Something changed since FC6, so i cannot figure out how to create simple bridges without dhcp for my xen domUs.
All what i want is:
xenbrINTERNET should bridge to eth1
xenbrLAN should bridge to eth0
eth0 and eth1 of my dom0 should also have an IP Address.
I do not want routing or nat for my domUs.
Thanks!
regards,
christian

Guest VM dropping connection.
by Ubaidul Khan
I am running RHEL5 Guest and Host. The guest OS is dropping network
connections occasionally(I noticed my ssh session suddenly terminated). The
guest is configured with private network interface and a public network
interface. Following are the bridge/network settings for the host:
bridge name bridge id STP enabled interfaces
xenbr0 8000.feffffffffff no vif2.0
vif1.0
peth0
vif0.0
xenbr1 8000.fefffffffffe no vif2.1
peth1
vif0.3
xenbr1 is dedicated to provide the private network link for the guest os.
Following is the guest OS configuration:
# Automatically generated xen config file
name = "saleen_webvm0"
memory = "1000"
disk = [
'tap:aio:/vms/img/redhat/linux/es/5.0/x86_64/saleen_webvm0.img,xvda,w','phy:/dev/sdc,xvdb,w'
]
vif = [ 'mac=00:16:3e:2e:6f:e1, bridge=xenbr0','mac=00:16:3e:2f:9e:b1,
bridge=xenbr1',]
# vif = [ 'mac=00:16:3e:2e:6f:e1, bridge=xenbr0',]
vfb = ["type=vnc,vncunused=1"]

domUs become unaccessible running 2.6.20-1.2962.fc6xen on host
by Asrai khn
Hi,
We have recently update kernel-xen on all of our hosts (3) and its vms all
running fc6. kernel-xen 2.6.20-1.2962.fc6xen is doing good on two hosts and
all its vms (10), however its giving lot of problem on third host.
when i reboots the host into latest kernel-xen the domUs become unaccessible
in a while hardly run for 10 minutes, 'xm list' still shows there status but
i can't access it from outside.
We are using loop back files for domUs File system, for testing i rebooted
host into last working kernel 2.6.20-1.2952.fc6xen and domUs into latest
kernel-xen and its doing pretty good, which mean latest kernel-xen is only
giving problem at host side.
when running 2.6.20-1.2962 on host it giving this in /var/log/messages

Running SLES 10 as pv guest in Fedora 7
by Felix Schwarz
Hi,
I tried to run a SLES 10 installation as (pv) guest in Fedora 7 but the guest
does not start.
First, I installed SLES using HVM which was somewhat slow (due to Suse's
graphics mode) but worked. After that I installed kernel-xen from the SLES
install media.
I found Gerd Hoffmann's very helpful page
http://et.redhat.com/~kraxel/xen/suse-guest.html and tried to incorporate his
suggestions regarding the domUloader.
My current config:
-----------------------------------------------------------------
name = "sles10_64_test"
memory = "512"
disk = [ 'tap:aio:/var/lib/xen/images/sles10_64_test,hda,w', ]
vif = [ 'mac=00:16:3e:4a:f5:f0, bridge=eth0', ]
vfb = [ 'type=vnc,vncunused=1' ]
uuid = "b1fd65e84128ced2dc435bb9d2e1861e"
bootloader="/tmp/sles-install/domUloader.py"
bootentry = "hda2:/boot/vmlinuz-xen,/boot/initrd-xen"
vcpus=1
on_reboot = 'restart'
on_crash = 'restart'
-----------------------------------------------------------------
/tmp/sles-install/domUloader.py exists and is executable, SElinux is configured
as permissive.
I guess something is wrong with the bootloader, from /var/log/xen/xend.log:
-----------------------------------------------------------------
2007-07-26 19:28:47 4590] DEBUG (XendDomainInfo:1463) XendDomainInfo.constructDomain

(xm command hangs, nothing happens anymore, have to kill the guest)
-----------------------------------------------------------------
Did anyone manage to run SLES {9,10} as pv guest?
thank you for reading :-)

Possible to delegate hardware to domU?
by Arik Raffael Funke
Hi,
is it possible to hide hardware from dom0 and delegate it to a domU with
the out-of-the-box Fedora xen? I.e. with pciback. I would like to
delegate a network interface to one of my domU's. Can anybody confirm
either that it is or that it is not possible?
Thanks.

AMD Opteron Quad Core CPU Availability
by Robert L Cochran
Can anyone suggest a good retail source of AMD Opteron CPUs when the
quad core versions become available? Also what would be a good
motherboard for these CPUs. I assume the quad core units (all versions
and price levels of them) support full virtualization.
Thanks

SElinux causes kernel bug on F7(?)
by Felix Schwarz
Hi,
after upgrading my SElinux on Fedora 7 (x86_64) to selinux-policy-2.6.4-28.fc7
and selinux-policy-targeted-2.6.4-28.fc7, I can't start Xen guests anymore.
Every time I do 'xm create xenguest' I get a message "invalid opcode: 0000 [2]
SMP" on all consoles together with some long call traces in syslog [1].
Immediately before I updated SElinux, the guest creation failed due to losetup
policy restrictions. After the update, I get "invalid opcode" messages. If I put
SElinux into permissive mode, I can at least start the xen guest. I think it is
the same problem as in bug 248834 [2].
So my question is:
* Is it really SElinux which causes the problem?
* Are there other Xen users out there which can reproduce this problem?
* Is this the right list to ask this question or should I ask on the SElinux
list?
* How can I help to fix this problem?
Thank you very much

Kernel panic - not syncing: Attepmted to kill init!
by taoj2＠cs.rpi.edu
Hi,
While I use "xm create -c guestvm" to create the domain at Fedora Core 6,
the following error msg appears:
Kernel panic - not syncing: Attepmted to kill init!
This never happened before, when several guest domains are running with
CPU usage < 5%, and I was trying to create a new one. This time, the CPU
usage of the running guest domains are 25%, much higher than before, and
above error msg appears while I create a new guest domain. Is this due to
the reason of not enough resource can be allocated to the new domain? Any
clue?
Thanks.
Best
