Since upgrading from Fedora 6 to Fedora 8 my custom bridge script
stopped working. I need to have both eth0 and eth1 bridged into each
XM. My xen machines are just defined in old-style /etc/xen/foo
configuration files, like
vif = [ 'mac=00:16:3e:42:08:1d, bridge=xenbr0', 'mac=00:16:3e:
42:08:1e, bridge=xenbr1' ]
I've changed that to
vif = [ 'mac=00:16:3e:42:08:1d, bridge=eth0', 'mac=00:16:3e:42:08:1e,
but when I do a "xm create foo" I still end up with the new interfaces
on the wrong bridge!
# brctl show
bridge name bridge id STP enabled interfaces
eth0 8000.0030488c8a26 no peth0
eth1 8000.0030488c8a27 no peth1
xenbr0 8000.feffffffffff no vif1.0
xenbr1 8000.feffffffffff no vif1.1
If I manually move the vifX.X interfaces to the eth0/eth1 bridges then
This is my custom bridge script:
"$dir/network-bridge" "$@" netdev=eth1 bridge=eth1
"$dir/network-bridge" "$@" netdev=eth0 bridge=eth0

Is it possible to auto start domU's listed in /etc/xen/auto in a
particular order? I imagine it is, but my reading comprehension or my
searching skills suck, because I can't find anything about this.

I am newbie to Xen. I installed xen-3.1.0-13.fc8 on fc8 and configured two fedora guest domains, one with virt-manager and the other with virt-installer. Both the virtual servers are up and i can boot them successfully, but both the installation didn't create the guest configuration file in /etc/xen directory(docs says configuration file will be created here).
Can anybody please help me to find out those files??
Thanks in advance.

I am looking for open source application that does similar to NC
states Virtual Computing Library (VCL) for xen management. I have
seen ovirt.org, but it seems to require hardware virtualization, which
I don't have.
any pointers will be appreciated.
I've just had a go at installing the Debian 4.0 jailtime image on a
Fedora 8 Dom0, but had no luck. I've just posted on the xen list about
this, but the summary is that the debian image has an empty /boot
directory, the jailtime config file doesn't use pygrub, and the config
file expects to find "/boot/vmlinuz-2.6-xen" on the Dom0, which of
course I haven't got on Fedora 8.
Has anyone had any luck installing prebuilt "foreign" distributions on
Fedora 8, or do you all roll your own DomU's?
If you have found any usable images, can you give me a URL? I'm looking
for Debian 4.0 or Centos 5.0 or, failing that, Ubuntu 6.0.6 or Gentoo
I haven't tried virt-install because the FC7 docs say "With Fedora 7,
installation of Fedora 7 guests using anaconda is supported". Presumably
this means that it doesn't work for non-Fedora DomU's?
What I am trying to do is add additional memory or CPU's to a running xen
guest that is already at the maximum allocated from build time. Currently, I
edit the config file for the guest and increase the memory or cpu and then
shutdown and start the VM. What I would like to do is re-read the config
file without having to restart the server. Does anyone know of a way to do
this, if possible?

I have an FC8 Dom0 which has identical setups for a Centos 5 and an FC8
DomU (both HVM). However, I can't mount a (file) DVD on the FC8 DomU,
but I can do this on the Centos 5 (and various other) DomU's.
The FC8 config file contains:
disk = [ 'phy:/dev/VG_Guests/FC8-64-001,ioemu:hda,w' ,
The Centos config file is identical, except that the 'FC8' strings are
changed. FC8 installed Ok using this cdrom line, and it also boots up
from this "DVD" if I change the boot order in the config file.
The FC8 DomU /etc/fstab contains:
/dev/sr0 /media/dvd auto
pamconsole,fscontext=system_u:object_r:removable_t,exec,noauto,managed 0 0
This line is identical for the FC8 Dom0, the Centos 5 DomU, and the FC8
DomU, except that Centos 5 uses /dev/hdc instead of /dev/sr0.
Any ideas why I can't mount the DVD on the FC8 DomU? mount reports that
the filesystem is read-only, so it's getting some of the way there, but
it then complains that the options are wrong:
> mount: block device /dev/sr0 is write-protected, mounting read-only
> mount: wrong fs type, bad option, bad superblock on /dev/sr0,
> missing codepage or helper program, or other error
I've tried various different options and filesystems without luck. The
DVD disk file itself is Ok, because I can still boot up from it.
One other thing I tried was changing the cdrom line in the config file to
but this doesn't help - after booting, the FC8 DomU doesn't have a DVD
at all in /dev; the /dev/sr0 and /dev/cdrom entries have disappeared.
