RE: [Fedora-xen] RE: Upgrading Xen machines
by Formoso, Travis
OK I am back from vacation and have started up this project again. I am taking old xen images from Fedora Core 4 and upgrading them to 7 on a new server. Here is what I have done so far and have run into a problem.
I installed Fedora Core 7 on the new server and has new xen and kernel. I transferred the old images and files from the old server to the new one.
I then went in to the old config file - and changed the kernel from FC4 to the new vmlinuz FC7. I then created a new initrd with xenblk with the following command: mkinitrd -v -f --with=ext3 --with=xenblk /boot/initrd-2.6.20-2925.13.fc7xen.img 2.6.20-2925.13.fc7-1xen. I put that in the config file under ramdisk.
Now when I run the command xm create -c xmconfig I get this:
Using config file "./xmconfig".
Error: Device 0 (vif) could not be connected. Hotplug scripts not working.
I looked at the archives and tried many suggestions, however none of them have worked -
Anything else I could do to get by this error?

Fedora7 / Bridge instead of NAT
by Harald Schwier
Hallo,
My xen 3.1 dom-0 host uses a public IPv4 address and i want to configure the
virtual machines with public addresses to.
By default, the Fedora 7 network Interface virbr0 is configured with a
private IPv4
address (192.168.122.1).
How can i switch from NAT to bridged networking?
Configuration in /etc/xen/xend-config.sxp :
...
(network-script network-bridge)
...
Thanks in advance,
Harald

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 :-)

xen networking
by Mark Nielsen
Since I have not yet been able to resolve my complex networking issues
in RHEL 5, I decided to upgrade 1 of my cluster nodes to 5.1 beta and
take this new libvirt networking for a spin. I'm not sure if this is
going to make my issue easier to resolve, or add to the complexity so
I'm writing this e-mail to hopefully get some suggestions as how to
proceed.
My network looks like this:
eth2 & eth3 comprise bond1
bond1 has bond1.48 - my public VLAN interface with an IP for dom0
bond1 has bond1.20 - my VLAN for some domU systems, dom0 has no IP on
this VLAN
bond1 has bond1.21 - my VLAN for some domU systems, dom0 has no IP on
this VLAN
I want to bridge to bond1.20 from some domU systems, and bond1.21 from
other domU systems. dom0 should not have an IP on these VLANs.
1) do I need to define a network interface in
/etc/libvirt/qemu/networks/ for each VLAN? (bond1.20 and bond1.21)
1a) If yes, do I need to have an IP address for the bond1.20 and
bond1.21 interface defined in
/etc/sysconfig/network-scripts/ifcfg-bond1.20 and bond1.21?
1b) Do I also need to define an IP address on that VLAN in the .xml
file for that network?
or
2) Can I just have 1 default.xml network and then use iptables to
forward to a specific VLAN based on bond1.20 and bond1.21 configured in
/etc/sysconfig/network-scripts/ ??
#2 would be best, if possible. Unfortunately there's not a lot of
documentation out on the new networking methods. I've read
http://watzmann.net/blog/index.php/2007/04/27/networking_with_kvm_and_lib...
but that doesn't get in to all the VLANs and bonds.
Any help is greatly appreciated!

i386 domU on x86_64 dom0
by Ask Bjørn Hansen
Hi everyone,
Most of our virtual machines could happily be i386 (and save a bit of
memory). I prefer the dom0s to be x86_64 for some added flexibility
for applications that do need 64bit (MySQL, memcached, varnish).
I upgraded one of our boxes to F7 to get Xen 3.1 since it's supposed
to be possible there. But it crashes pretty fast every time. I am
running the latest kernel and xen in the dom0 and just the release
tree in the domU.
Any ideas?

Install location for FC7 as a guest
by Joseph Hesse
Hi,
I am using 'virt-manager', paravirtualization, to install FC7 as a guest
under FC7. I can't seem to find a network install location that works.
The Fedora site list many ftp and http mirror sites for installing. I can
ping them and verify they are alive. My problem is I don't know how deep to
go into the directory tree to get something that anaconda likes.
I tried 'http://download.fedora.redhat.com/pub/fedora/linux' The error
message I get is "Unable to complete install: Invalid URL given."
Can I take the FC7 DVD, mount it and then ftp to it?
Thank you,
Joe Hesse

Xen on FC7 and bridge not on eth0
by Andrzej Nakonieczny
Hi
I'm looking for informations about networking in Xen on FC7. I'm trying
to change default bridge device from eth0 to another one. On RHEL5 Beta2
I did change only one line in xend-config.sxp to:
(network-script 'network-bridge netdev=dummy0')
and it worked fine. But on FC7 it doesn't work. So what is the right way
to bridge all Xen domains to dummy0?
I tried to add my own script instead of network-bridge and vif-bridge
but after some changes virt-manager stops with segmentation fault.
So is there any way to change default settings?
Regards,
Andrzej

Upgrading to 2.6.20-1.2999 Fedora Core 6
by Peter Teoh
After updating my system, the kernel change from 2.6.20-1.2962.fc6 to
2.6.20-1.2999xen.fc6, and my original Xen installation now cannot have
xend started, giving rise to the following errors instead.
Why and please help. Thank you very much!!!!
