PAE kernels not working but non-PAE does
by Jason Tower
i have several dell poweredge 2650s with 4gb ram (these are 32 bit
xeon cpus) running fc5 w/ the 2.6.17-1.2174_FC5xen0 kernel, the domUs
are ubuntu dapper images booting the 2.6.17-1.2174_FC5xenU kernel.
everything works beautifully, very stable.
i was hoping to squeeze some more domUs on these systems by adding
additonal ram and using the PAE kernels. unfortunately booting
2.6.17-1.2174_FC5xen in the dom0 breaks networking (the bridges are no
longer created) and the domU won't boot at all (kernel panic, can't
find /dev/sda). i've also tried the latest fc5 kernel and the stock
fc6 kernel and get the same result. i've copied
lib/modules/2.6.17-1.2174_FC5xen to the domU's root filesystem and am
using the matching initrd but no joy.
is it possible to make this arrangement work?

Upgrade warnings FC6 x86_64 (with xen)
by Bill Davidsen
I just did an install of FC6+xen, and I'm not sure if xen is involved in
the problem or not. After I did the initial install and rebooted, I
checked the list of updates
yum check-update | tee update.list
and found updates for the kernel, yum, and virt-manager. Doing the
updates cautiously (I have been seeing upgrade problems), I got:

W2K CD installation error on guest
by Jimison, Ed
I've been trying to install W2K on Fedora Core 6. I found a previous
post that recommended using "Standard PC" and this helped me get past
the original problem with a hung black screen. The next problem I'm
running into is that once the Windows installer boots and begins the
"Installing Windows" step, I immediately get this error window:
Setup was unable to access files need to continue. This could be caused
by an error on the CD Media or the CD is no longer present in the drive.
Any advice?
Thanks,

What should the context of /var/lib/xen/images be?
by Bill Davidsen
I'm trying to use hvm and having issues... I'm checking permissions now.
What is the proper context (ls -Z) for the /var/lib/xen/images
directory? On my last install I put it on another partition, in hopes of
trying images I create with i386 on the x86_64 environment later. But
the directory is just a plain directory, I suspect the context was set
on the directory in the root filesystem before I did the mount. That
system is shut down now as my test room is on a small UPS and we are
having a thunderstorm.
And should it matter if the files in the directory are of the proper type?

Re: [Fedora-xen] Mouse out of sync on guest machines
by Robert Thiem

I was pretty traumatised by this when I first ran the FC6 guest install.
It works like this:
- X drivers on the guest are expecting regular mouse movement signals (eg
"The mouse is moving left, fast")
- VNC provides absolute mouse coordinates (X,Y)
- XenFB tries to translate the two, but can't sync the pointers well
because it gets no signals back from the guest about the absolute position
and pointer accelleration.
After installation the mouse pointers can be aligned pretty well by
setting the mouse accelleration on the guest so that they move at the same
rate. You then need to chase the pointer into a corner to align them. This
way the guest accelleration matches the arbitrary value XenFB is using.
During installation I've found it's best to turn the mouse accelleration
right down on the *host*. I found that this would let me move the *host*
mouse pointer to the middle of the VNC window to give me fairly free
movement on the guest pointer.
Unfortunately this is going to persist until some method is put in so that
either the guest X server can accept absolute coordinates (a virtual
absolute position pointer device it understands) or there's some for the
host to find out where the guest pointer is. I believe that work is being
done on this now, but we'll have to be patient with it.
SDL probably has the same issue, but I think it can "grab" (hold) the
mouse pointer so that it doesn't run out of the window in the same way it
does with VNC. It does this with fully virtualised machines from what I've
seen.

virt-manager (with dbus) hangs
by Felix Schwarz
Hi,
I'm running Xen on a Fedora Core 6 x86_64 machine (AMD X2). After installing the latest
updates today, virt-manager does not start anymore when run as root. Xen still works, I
can start/stop guests with the xm command.
example:
[root@ws2 fs]# virt-manager
... hang
However, if I start it like this, everything works:
[root@ws2 fs]# virt-manager --no-dbus
I don't have clue where to look for the error. Are there any diagnostic tools for dbus?
