Win Xp 64 bit install
by Abhishek Gaurav
Hi,
I am trying to install windows xp 64 bit (trial version) using
virt-install on a fc6 system. The installation seems to stall when the
message in the vnc console says "Setup is starting windows".
The xm dmesg shows:
(XEN) (GUEST: 13) Booting from CD-Rom...
(XEN) (GUEST: 13) unsupported PCI BIOS function 0x0E
(XEN) (GUEST: 13) int13_harddisk: function 15, unmapped device for ELDL=81
(XEN) (GUEST: 13) *** int 15h function AX=E980, BX=00F2 not yet supported!
(XEN) (GUEST: 13) *** int 15h function AX=EC00, BX=0002 not yet supported!
(XEN) Trying to set reserved bit in EFER: 4d01
The last message "Trying to set ... " actually comes up just before it
stalls.
What might be causing this ?
I have also tried to install an older Win Xp home sp1, which actually
goes past the above messages (without "trying to set ...") but ends up
in the famous black screen upon first reboot.
It'll be great to know what might be causing the above problems.
Thanks,
Abhishek.

initscripts, xen and bonding
by Axel Thimm
Hi,
I'm having a hard time getting bonding to work on FC5t3. It looks like
the bond0 interface bond0 is renamed to pbond0 by xen [*] and the
enslaving does not work anymore then. It works if I log on the
terminal and ifenslave the devices to pbond0 instead of bond0 after
the boot process has finished.
But I want this to be handled automatically during reboots, so I tried
assigning the bonding slaves to pbond0 as a master in the
ifcfg-eth{0,1} scripts, but that doesn't work.
What is causing the bond0 rename and should this renaming be
considered by initscript? Is this a user error or should I file this
against bugzilla? xen or initscripts?
Thanks!
[*] The only reference I found was a Japanese site and google's
translation of it.

Re: [Fedora-xen] xen in fc6
by Adrian Revill
Hi Henk,
For the NFS problem, have you tried testing the nfs mount by mounting it
back on Dom0
When i first set mine up i logged in as root on Dom0, created a dir
called testmnt then mounted the nfs on it.
In your case #mount 192.168.0.1:/fc_5 testmnt
You should then see all of the install tree under testmnt
The other thing, is look in /var/log/messages on Dom0, you should see
the mount attempt from your DomU
I also run with no firewall, is yours on? is it blocking the mounts?
You other problem
The startup works ok until the following error: "error: failed to
retrieve FC_5/Fedora/base/stage2.img"
I guess the file is actually there? try extracting it from CD again, maybe its corrupt.
regards
Adrian

NAT Problem
by Jim Klein
This may not be specifically a xen problem, but I am having an issue with running a xen vm as a NAT gateway. Basically, the situation is this: Dom0 is set up with 2 bridged ports, xenbr0 and xenbr1. xenbr0 is on the public network and xenbr1 is on the private (10.x.x.x). DomU #1 is setup as a router using both interfaces, eth0 public (xenbr0) and eth1 private (xenbr1) with NAT via iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE. Now, if I bring up another DomU (#2) on the same box with only 1 interface (eth0) on xenbr0, it is completely inaccessible by machines routing through DomU #1. However, ssh into DomU#1, then ssh into DomU#2 from the DomU#1 console works. Further, if I migrate DomU#2 to another box, it is suddenly accessible to machined routing through DomU#1. Thanks in advance for any help.

Problem about installing guesting OS with virt-manger of Fedora Core 6
by taoj2＠cs.rpi.edu
Hi,
Thank you guys a lot.
This time I didn't create the file manually. Just Let the virt-manager to
do this. First, I try to use /home/jane/xen/box1, but it failed.
So according to Dan's suggestion, I use /var/lib/xen/images/box1 as the
storage location of guest OS.
But why this file has to be under /var/lib/xen/images rather than /home? I
didn't realize this problem when I was intalling the guesting OS before.
Only /var/lib/xen/images is a valid directoy? Is there any other valid
directory?
And I found another problem even if I use /var/lib/xen/images/box1 :
"The partition table on device xvda was unreachable. To create new
partitions it must be initialized, causing the loss of All Data on this
drive. This opeartion will override any previous installation choices
about which drives to ignore. Would you like to initialize this drive,
erasing ALL DATA?
"
So this means each time I want to install an guest OS, I have to create
new partition? It seems not good. :(
And I don't know how to solve this problem. This is the first time I use
Fedora Core and XEN. I want to do some experiments about the VM migration
with XEN.
Do you guys have any idea of above problem? Thanks a lot.
Regads,

iSCSI root
by Adrian Revill
Hi
Has anyone had any luck using iSCSI as the root device for a DomU.
Is it possible to specify the target address in the virt-manager
directly? as i have seen comments on google that it has to be mounted on
Dom0 first. Which kinda defeats the object of virtual storage for
virtual machines.
If i was doing a straight FC6 install i could select an iSCSI target as
the target drive.

Problem about installing guesting OS with virt-manger of Fedora Core 6
by taoj2＠cs.rpi.edu
Hi,
I installed the Fedora Core 6 on my computer.
Now I was trying to install the Fedora Core 6 guesting OS in my computer.
I use the Virtual Machine Manager to do this.
First, I create an empty file, box1, like this:
cat > box1
I didn't type anthing into the file. SO the file is empty. (Is this a
correct approach to create a file for the guesting OS storage space ?)
Then I set the /home/jane/xen/box1 as the storage space to install my
guesting OS. I chose Fedora COre 6 again as my guest os. The problem is:
When the installation comes to selecting disk partition part, there is no
available drive there. I print the screen and attached the picture.
I get stucked there and can't continue the guest os installation.
COuld you please give me some hint? THank you very much.
Regards,
Angel

XEN, FC6 - two networkbridges, problems with ssh
by Abri Nation
Hi @all,
i got two networkdevices (eth0, eth1), and i want to use the eth1 for DMZ
and eth0 for "normal" internetaccess, so i have to build to bridges.
on default FC6 created this bridge and "brctl show" shows the following
conifgured bridge:
-----------------------------------------------------------------------------------------------
bridge name bridge id STP enabled interfaces
xenbr1 8000.024103917534 no vif49.0
tap0
vif45.0
tap1
peth1
vif0.1
-----------------------------------------------------------------------------------------------
that bridge (xenbr1) i want to use know for DMZ. and the interface eth0 i
want to create
an new bridge for "normal" internetaccess, and my other VM. But if i will
configure this, it will
not longer be possible to connect to the XEN server with ssh (cause now, i
could only connect
the xen server on the eth0 interface with ssh. eth1 is not reachabel per
ssh, cause of the bridging).
My Questions are:
1. How could i build two bridges, one for DMZ and one for "normal"
internetaccess, having acces per ssh?
2. Is this default that the bridge interface is not longer available for
ssh? i thought in bridging interfaces,
the IP is copied from the interface to an virtual interface (e.g. peth1), so
it is possible to conntact the
physical interface also?
3. using FC6 with virt-manager - where can i change the bridge or build a
new one? only on the command line? (with the network.bridge script oder with
"brctl"?)
Could anyone tell me my failure,
or the mistake on my part?
Thank you very much for help!
kind regards,
Abri
