Particular domU boots before anyother domU on the same host
by Asrai khn
Hi,
I am wondering how to make sure that a particular domU boots before anyother
domU on the same host. For example this particular domU providing some samba
shares to other domU. Apparently if the dom0 reboots we have to 'mount' the
shares on some domU(s) which boots before domU which providing these
shares.
Any help in this regards will be highly appreciated.
Thanks. Askar

Guest install very slow
by Adrian Revill
Hi,
I have just done a clean install of FC6 with visualization on a single
cpu box (AMD 1.7+XP 1.5G ram)
The performance of the box running FC6 is fine, all the windows and
menus open quickly and smoothly.
I followed the FedoraXenQuickstartFC6 and all seems to work perfectly
except the guest seems to run very slowly.
The Virtual machine manager shows about 0.1% cpu use for the new guest
and Domain-0 stays about 4%
I have extracted the FC6 isos onto the same box and created a nfs mount
point for the source.
I am using /var/lib/xen/images/testOne as the directory for the disk
path with a 3G limit
I set 512Mb ram and 1CPU
The boot seems quite quick, and anaconda starts, all the selection of
the language and keyboard seems ok too.
Then it sits for about 15mins with Running Anaconda at the bottom of the
screen, then starts the x window. It takes about 1/2 hr for a X cursor
to appear, that will follow mouse movement, but takes a couple of
seconds to catch up.
I never have seen anything more. Just a black window, even after
leaving it all weekend.
when i run virsh list it always says the testOne domain is blocked.
I have looked in all the log files and the console, but there are no errors.
Anyone got any ideas? as i guess its not meant to be this slow.

Problems with starting xen guest (DomU)
by Eduardo Amaral
Hello All,
My XEN guest was not starting. It stopped after " ide: Assuming 50MHz
system bus speed for PIO modes; override with idebus=xx "...
Do you know what is going on ?
Thanks,

memory strangeness
by kadafax
Hi list,
I am a happy user of xen'ed fedora 6. It is working really well (fc6
domU on fc6 dom0). I have recently added memory to the server (Dell
Power Edge 2850, latest bios A06) from 2GB to 4GB.
And there is something strange with the total memory report from the OS:
[root@host ~]# uname -a
Linux host 2.6.19-1.2911.fc6xen #1 SMP Sat Feb 10 15:34:39 EST 2007
x86_64 x86_64 x86_64 GNU/Linux
[root@host ~]# cat /proc/meminfo | grep MemTotal
MemTotal: 3584000 kB
[root@krypton ~]# xm top
...
Mem: 4193664k total, 4184456k used, 9208k free CPUs: 4 @ 2992MHz
...
Why does it return different value with 'cat /proc/meminfo' and 'xm top'.
Should I worry about this?
Thanks,
Kfx.

Virt-manager and Migration
by Jim Klein
When I migrate a PV from one box to another, I lose access to the virtual console in virt-manager, even if i migrate it back to the original box. DomU is working fine, just no vfb console access (although xm console still works.) Any ideas out there for a fix?

xen windows already installed
by Chip Motley
Hello,
Is it possible to:
Setup a dual boot using WinXp and Fedora 6 ---- then boot into Fedora using
the xen kernel,
start the virtual manager and boot the windows operating system that is
already installed???
This would most likely require setting up a separate hardware profile within
windows.
I came across such an article (PDF) sometime ago, but now I can not
find/Google it.
Thanks Cmotley

FW: Problems installing Xen
by Chip Motley
Hello,
I set up my first dual boot with Fedora 6 and WinXp. The partitions were
setup as shown below. My problem occurred after the installation of Xen.
When I went to /boot/grub and looked at grub.conf there was no reference to
Xen. I ran "Xend start" and received the following message:
ERROR: Could not obtain handle on privileged command interface (2 = No such
file or directory)
ERROR: Could not obtain handle on privileged command interface (2 = No such
file or directory) Traceback (most recent call last):

I looked in the Yum.log and found the following:

How do I install Xen correctly? PS I am new to Linux

strange behavior.
by John Sanabria
Hi,
i'm compiling gt4 (Globus Toolkit 4.0.3) inside a virtual machine. That is
the commands that i had executed:
# make >& installer.log
^Z
# bg
# tail -f installer.log
time later, the make stop to do its job.
# jobs
[1]+ Stopped make >&installer.log
then, manually i have to re-run the command, with "fg".
The question is: Why programs (all or some of them) stop suddenly with no
apparent reason?
thanks a lot,
