xend hangs at start
by Eric Smith
Hi,
Running FC5 now on Pentium 4 and want to try xen (for the first time).
[root@gum ~]# xm list
Error: Error connecting to xend: Connection refused. Is xend running?
[root@gum ~]# ps -ef | grep xend
root 2343 1 0 22:33 ? 00:00:00 python /usr/sbin/xend start
root 2344 2343 0 22:33 ? 00:00:00 python /usr/sbin/xend start
[root@gum ~]# uname -a
Linux gum 2.6.15-1.1955_FC5hypervisor #1 SMP Wed Feb 15 16:21:02 EST 2006
i686 i686 i386 GNU/Linux
The "start" never completes. Disabled SElinux and rebooted, same results.
Any ideas?
Thanks,
Eric
ps Installed FC5 test 3 and then ran yum update to move to FC5 when
released. Updated again just today:
[root@gum ~]# cat /etc/fedora-release

"enhanced" xenguest-install.py
by Ben
I just finished testing my enhancements to xenguest-install.py that
let me specify multiple volumes and multiple NICs to export to the
new domU. Seems to work ok for me, though I'm only testing it on the
paravirtualized server. In case anybody else would find such a thing
useful, I've attached it here.
(Note that I gave up on the default bridging script. It just didn't
make sense to me when I wanted more than a single NIC. Instead, I
used the logic on http://wiki.xensource.com/xenwiki/XenNetworkingSuse?
highlight=%28XenNetworking%29 pretty much verbatim.)

Re: kudzu not seeing my new NIC
by Ben
Actually, I take back that part about using the interfaces just fine.
While I can *see* the manually configured interfaces just fine, it
seems the xen dom0 scripting glue plays with the arp broadcasts in
such a way as that an arp request for any interface always resolves
to just of of them.

RE: [Fedora-xen] setting IP address for domU in a config file

Start the domain and create a
/etc/sysconfig/networking/devices/ifcfg-eth0 file with the following in
it. (works for me!) This is on FC4 Zen 3.01
DEVICE=eth0

Subject: [Fedora-xen] setting IP address for domU in a config file
Hello,
I had followed the instructions in
http://www.fedoraproject.org/wiki/FedoraXenQuickstart
an I am succeeding in creating domain U.
The thing is that I want domU to start with some static IP address.
How can I do it ?
I had tried adding , in the config file for domU, vif = [
'ip=192.168.0.193', 'bridge=xenbr0' ] netmask="255.255.255.0"
and run "xm create -c domUconfig"
Dom U started , ifconfig -a showed eth0, but without the IP address.
Any ideas ?
Mark

Unable to reboot a domU
by Ben
I installed a domU on x86_64 today, and was very happy. I even logged
into it and saw that things seemed to be working, and all was well. I
tried to reboot it, and now the domU kernel panics every time I try
to boot. :(
The bug is 185603, and the console end with:
no fstab.sys, mounting internal defaults
Switching to new root and running init.
unmounting old /dev
unmounting old /proc
unmounting old /sys
Kernel panic - not syncing: Attempted to kill init!

So at present you couldn't create XenU with that image again? I think maybe your XenU image is broken.
Maybe you can do a manually mount that image file and check if /etc/fstab is there.
mount -oloop xenU_image_file /mnt

Problem installing FC5 guest in Xen on FC5 using xenguest-install.py
by Scott D Hankin
Howdy -
I'm attempting to install a FC5 guest in Xen on FC5, 2041 xen0 kernel. I've
gotten to the point where anaconda runs and starts presenting me with
menus. Unfortunately, the 3rd menu it presents is stopping me, the one
which sets the IP address.
If I select DHCP and networking is set up for NAT, it thinks for a bit and
then returns to the same page. If I try to manually specify an IP address,
it thinks for a bit, and then segfaults. If networking is bridged, it
segfaults in either case.
The command I'm running is:
xenguest-intall.py -n vm2 -f /root/fedora.img -s 6 -r 256 -p -l
ftp://mymachine
I've tried this with the networking setup as bridged or NAT, but the result
is always the same.
Any thoughts?

In the beginning, there was nothing, then God said, "Let there be light."
And there was light. There was still nothing, but you could see it a lot

crash booting rawhide xen0
by Andy Burns
Hi there,
I've not been updating my xen kernels to *every* recent rawhide release,
but did so today, to 2.6.15-1.2041_FC5xen0, my first two attempts to
boot this xen0 crashed and stackdumped :-(
Having seen it fail twice, I attached a serial console and was preparing
to capture that with console=ttyS0,115200, but on the next two boots the
crash didn't happen, however my console output still went to the
vgaconsole, does xen have a different way to use the serial console?
I'll gladly log a bug if I can make it happen again ...
Also I've just tidied up my grub.conf, /boot/ and /lib/modules/ to get
rid of heaps of old kernels that the switch from guest/hypervisor to
xen0/xenU had left around, is there anywhere I can get back a few
slightly older kernels to try and find out what version caused this
breakage? I think my last known good version was kernel 2032

RE: [Fedora-xen] crash booting rawhide xen0
by You, Yongkang
Hi Andy,
I suggested that you can do "yum update" to update other RPMs and retry too.
I didn't meet this problem in x86_64, after I do yum update to catch up latest development tree. :)
