Problem installing full virtualized Vista guest
by Jimison, Ed
Now that I finally got W2K installed as a guest, I'm moving on to Vista.
The initial setup and config worked and the Vista install booted from
CDROM and transferred files to the harddrive. After reboot there is just
a blank black screen, which is very similar to the W2K install. With W2K
I worked around it by hitting F5 and selecting Standard PC. With Vista
there is no such option.
I transferred the ISO to disk and added it to my config file. When I
create the guest and it tries to boot I get this error:
Boot from Hard Disk 0 failed
FATAL: not a bootable disk
My config file:
# Automatically generated xen config file
name = "vistavirt1"
builder = "hvm"
memory = "500"
disk = [ 'file:/xen/vistavirt1,hda,w',
'file:/home/evjimiso/vista.iso,hdc:c,r']
vif = [ 'type=ioemu, mac=00:16:3e:3f:17:66, bridge=xenbr0', ]

console only on fedora?
by Tom Horsley
I just successfully got a paravirtualized openSUSE 10.2 system
running as a guest under Fedora Core 6 (x86_64 all around).
I did it by installing suse in native mode, then editing
the /boot/grub/menu.1st file to boot the xen kernel by default,
then tweaking the config file I had laying around from a
previous test to define the physical disk partitions the
same way in the guest as they are in the host.
This all worked (much to my amazement :-), but when I try
to open the console from virt-manager, it tells me
"Console not available".
Is the console implemented by some special kernel module I
probably don't have in the suse xen kernel? Just trying to
learn how all this stuff fits together...
(Not really a critical bit since I can access the guest
just fine via the network).

etho disappears in dom 0 FC6
by jean-marc pouchoulon
After rebooting on a xen-kernel FC6 (2.6.28-1.2860.fc6) , eth0 NIC
device is not available.
Rebooting on a non xen kernel it re-appears.
Any ideas ?

smp fully virtualized system?
by Tom Horsley
I was playing with xen on monster server at work (4 dual core opterons).
I've got FC6 x86_64 Dom0 on it, and tried to install a fully virtualized
FC6 i386 guest (to test running 32 bit kernels).
I first tried telling it to use 2 cpus for the new machine
(creating it via virt-manager) and when the installer
loads the initial linux kernel from the boot DVD, it just goes
into a blank stare right after the kernel mentions it is
bringing up 2 cpus.
If I try again and tell it only 1 cpu, everything works great.
Is this any kind of know problem? Should I report a bug anywhere?

Keyboard in fc6 guest
by Lee Hornby
Hello all
Fc6 guest under fc6.
UK Keyboard.
All keys map fine in Dom0 but in DomU some keys don't work or are wrong
and can't get the | pipe key which is somewhat annoying.
Have check keyboard in gnome is set to UK and Language is UK.
If run with a console and sdl get the following when pressing the keys
in question.
keyboard.c: can't emulate rawmode for keycode 0
Am I missing something obvious?

understanding perfomance
by Ben
I'm having a hard time understanding how to determine load on my
domUs. I'm running FC5 on both my dom0 and domUs, all up to date
against the official fedora repositories as of last night. On at
least one of my domUs acting as a database, xm top shows CPU load at
roughly 60% when I fire off some long-running queries. That sounds
reasonable to me, but running top of the domU itself shows almost no
cpu load. The domU *is* doing a lot of I/O, but according to vmstat
on the domU, very little of the processors are stuck in I/O wait state.
So, I'm not sure what the proper question is. It's probably some
combination of these two:
1. Why does the domU not think it's stuck in I/O wait?
2. Why does xm top and top on the domU disagree?

Problems with guest Dom's on Fedora 6
by . .
Hi,
I'm new to Xen. I've been trying unsucessfully to setup an x86_64 guest on
my x86_64 Dom0 (both running Fedora Core 6). The dom0 system is a fresh
install of FC6 with latest updates applied.
What I have been able to do is run the 'virt-install' utility to create the
guest environment, however when the FC6 install finishes on the guest, it
says 'rebooting' and then dies i.e. I can't see the guest listed when I do
an 'xm list'.
What I've then done is 'xm create -c /etc/xen/fc6_64' (the name of the
config created above) which takes my to the pygrub boot screen, then
attempts to boot, however I only get as far as 'creating root device' and it
stops. Now, when I do an 'xm list' I can see the guest listed but it is in
the 'blocked' state. The xend.log file doesn't appear to show any errors,
just a whole lot of DEBUG - the last message is 'INFO (XendDomain:370)
Domain fc6_64 (1) unpaused'
Now if I try to reboot the guest i.e 'xm reboot fc6_64' things go horribly
wrong. The guest console says 'restarting' then drops back to Dom0 command
line. When I do 'xm list' I get the error 'Error: Device 51712 not
connected' instead of the usual list and xend.log shows the following:
