Subject: [Xen-users] Debian etch Xen: No display window.
I am trying to setup Xen virtual servers using a Debian etch
with the xen
3.0.3 provided in 32 bits mode. I am using full virtualization.
I managed to get things started using the configuration
provided below. I
was able to run the install (with boot="d"). I even managed
to start the
system afterwards, and it runs correctly.
But now I encounter a problem I already hit when running 64
bits kernels (I
am running now 32 bits, as I was told xen support for 64 bits
was much
better since 3.0.4).
The xen domU starts, but it does not display the SDL window anymore.
It did it a few times, for installing the system for instance, with
everything runnig perfectly OK, connecting to a network
mirror for the
install. It runs really well!
The only way for me to make it appear again is to remove the
type=ioemu from
the vif. But then the system does not recognize anymore the
net card, which
seems reasonable.
I think (but I'm guessing) that you can't specify an IP-address to a
IOEMU network card. This probably confuses QEMU, which is responsible
for getting the SDL/VNC window to appear. You may want to check the
/var/log/qemu.<pid>.log for the QEMU that is runnning the guest (doing
"ls -ltr /var/log/qemu*" will show the last one at the end of the list -
if you get a HUGE list, you may want to delete the older ones!)
If I don't specify the IP address in the vif line, the device vifN.0 is
assigned an address 10.X.X.X, which is not what I want. But can I specify it
the way I do?
Here's the content of qemu log:
(Note that I am using network-nat)
# more /var/log/xen/qemu-dm.5435.log
domid: 5
qemu: the number of cpus is 1
/etc/xen/scripts/qemu-ifup: could not launch network script
Could not initialize device 'tap'
It was very helpfull to me. Googling for it, I encountered the page
http://www.brandonking.net/blog/2007/02/xen-routed-network-shorewall-qemu.html
Which shows some troubles with networking that in turns point to
http://lists.xensource.com/archives/html/xen-users/2006-12/msg00448.html
Which is the same problem. I found that tunctl is a tool provided with
user-mode-linux packages. And after running the command 'tunctl -t tap0' and
commenting out the brctl line in qemu-ifup, the SDL window shows up again.
Now the network card is fonud by the domU, but it does not work. I cannot
ping the dom0 from the domU, neither the other way round.
Also, I now got a tap1 interface showing up with ifconfig whenever my domU
is started. But networking does not work.
And qemu log is now:
----------------------------------------
# more /var/log/xen/qemu-dm.10633.log
domid: 12
qemu: the number of cpus is 1
shared page at pfn:7fff, mfn: 305d5
buffered io page at pfn:7ffd, mfn: 305d7
False I/O request ... in-service already: 0, pvalid: 0, port: 0, data: 0,
count: 0, size: 0
---------------------------------------
And google isn't very helpfull with it ...
brctl show does not show any bridge. Is this normal? (using vif-nat)
Do I have to configure tap1 in /etc/network/interfaces?
Still many questions indeed.
Trying to understand ...
Thanks for your help.
