Bridge network configuration
by Jordi Prats
Hi all,
I've installed a Fedora 7 with Xen. I found that every physical
interface that I configure to have a bridge attached using the folowing
command disappears.
vifnum=0 bridge=servei netdev=eth0 /etc/xen/scripts/network-bridge start
If it disapears I can'nt set an IP on dom0. Anyone has encountered this
issue?

Re: FC7 MOUSE PROBLEMS
by miguel
Thanks for submitting the bug report. I reported this problem over 4 months
ago, but I never created a bug for it. This problem occurred on 3 different
DELL systems I was working with ( 2 laptops and 1 desktop). I'll try your
workaround to see If it works on my systems.
Thanks

Hide the host
by nooroon
Hi all,
I'd like to use xen with fedora as host, and several OSes as guest (in fact
2).
The aim is to use the host as a router for the guests.
So i'd like to make the host as thin as possible, in order to provide most
power to the guest. Do you know a smart way to do so?
I'd also like to hide the host from the user. When the user log in the
host, a script is launched, and the appropriated guest start in full screen.
Does anyone has already done something similar?
thanks for all.

SET failed on device eth0 ; No such device
by Jordi Prats
Hi all,
I'm getting this error while trying to bring up my eth1 (is not a
wireless card, is a Broadcom NetXtreme II BCM5708 Gigabit Ethernet)
Error for wireless request "Set Encode" (8B2A) :
SET failed on device eth1 : No such device.
SIOCGFFLAGS: No such device
Failed to bring up eth1.
Anyone knows why is trying to setup a Gigabit ethernet as a wireless
card? My /etc/sysconfig/network-scripts/ifcfg-eth1 is:
DEVICE=eth1
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=172.16.1.148
GATEWAY=172.16.1.1
TYPE=Ethernet
Thanks!
Jordi

I have managed to reproduce it without using the Eclipse-based
application.
I simply create a new full-virtualization guest (using virt-install)
while moving heavily the mouse cursor. It will eventually get stuck in
the left side of the display, when the vncviewer Window is shown.
Restarting the X server solves the problem most of times, but I managed
to get the cursor stuck on the left if I move the mouse heavily while
the X server is restarting.
I have found a workaround, also:
'xset m 1/1 1000' (in practice it will disable the mouse acceleration
by setting a huge threshold) make the cursor behave properly. Enabling
mouse acceleration again gets the cursor stuck again. This makes me
believe that this is a Xorg bug, but that may be triggered more easily
when running Xen.

Hey, this is EXACTLY the same behavior!!!
Actually I think we are facing the same problem.
I can move it to the right slowly too.
This sounds really similar.
Unfortunately, in my situation it is reproducible as it happens every time
:(
In fact, nothing runs within the host FC7 except Xorg.
I thought it might have been a window manager problem as bonobo doesn't
start anymore when xen is launched... so I shifted from Gnome to XFCE but
this didn't change anything.
So, apart from Xorg and rdesktop, nothing runs in FC7, everything runs
within the hosted Win XP.
What bugs me most is that it doesn't appear when launching anything in
particular: I'm simply quietly working in my Windows session and all in a
sudden, the pointer gets stuck in the left.
Well, this is not that dramatically annoying as I can still use the
touchpad, but still it's frustrating: I'm the mouse type, not the touchpad
one ;-)

I had this weird cursor behaviour last week, on Fedora 7. I was running
a Xen kernel, also (2.6.20-2931, probably; but it could be a different
version).
If I recall correctly, I didn't have any guest running at the time. It
happened when I started an Eclipse-based application[1]. The cursor
could be moved to the right, but only if I moved the mouse very slowly.
On my case, it was a desktop machine, so I didn't have a touchpad,
just an USB mouse.
However, I didn't manage to reproduce the problem today. Is it easily
reproducible, on your case?
[1] It was a IDE from QNX I had just installed for testing.

Mouse problem with FC7 uptodate, Windows XP virt machine, rdesktop connection.
by NoisilySilent
Hi,
I used to run Windows XP inside a XEN virtual machine on FC6.
Everything was perfect.
To connect to the Windows XP virtual machine, I used to run rdesktop.
Today I installed FC7 from scratch and tried to use my Windows XP virtual
machine and I noticed a very strange behaviour:
All of this stuff runs on a Dell Latitude D620 laptop.
This laptop offers a touchpad, a trackpoint and of course USB ports on which
I connect a 3 button wheel mice.
FC7 is up to date and all packages are at last date version, including XEN.
Now when I connect to the Windows XP virtual machine via rdesktop, after a
few minutes the trackpoint and the mouse get weird: when using either the
trackpoint or the mouse moving rightwards, the pointer gets "stuck" on the
left border of the screen whereas I can still use the touchpad and things
don't get messed up.
However, when using FC7 without XEN, I don't encounter this trouble.
Have you ever heard of such a problem?
Cheers

Problems installing DomU on a new system using virt-manager
by John Arthur
Fedora 7 - fully updated with yum.
I've just built a new x86_64 system Intel Duo Core 2 E6420 on an Intel
DG965WH mb.
There appears to be a major bug (amongst many others) in virt-manager
which only appears when installing the very first DomU.
If I try to install the first DomU connecting to a virtual network the
install fails every time right after I configure the network interface
when retrieving stage2.img. It just hangs restarting the DomU results in
a boot failure message.
If I install the first DomU using a shared network the install is
successful. Now for the fun part. If then I delete the DomU supposedly
returning to a clean slate I can now install DomU's using a virtual
network.
It appears that installing the first DomU using a shared network changes
something that causes virtual network DomU's to install successfully
even if the first "shared network" is simply installed and then
immediately deleted.
Does anyone have any suggestions as to what might be happening?
Does virt-manager use any install scripts, if so can they be customized?
Regards John
