XEN and Raid
XEN and Raid
I've installed a new Gentoo server and am having a bad time trying to configure XEN using RAID1.
RAID 1 is already working on my server, and XEN is also installed.
The problem is when I try to start a domU it wont find the md devices,
causing a kernel panic: Unable to mount VFS....
I'm running xen-sources 2.6.18 and kernel is working fine.
The only problem is that the image cant find the md raid device.
Any idea?
Thanks in advance.

You have to post more info on your domU. Like the config file ...
Antonino Catinello | http://catinello.eu
This is the config file:
# SCRIPT PARA DOMINIO VIRTUALIZADO
kernel = "/home/virtual/xen-kernel/kernel-2.6.18-xen"
memory = 1024
#builder='hvm'
name = "garopa"
disk = ['file:/home/virtual/xen-images/garopa.img,md4,w']
root = "/dev/md4 ro"
vif = [ 'ip=X.X.X.X, vifname=eth5', " mac=00:16:3e:06:60:20, bridge=xenbr0 "]
vcpus = '1'
The /home/virtual is my sda4 -- as raid: md4. It is mounted and working.
I cant get domU to boot because it wont find the root partition.
Thanks!

Why don't you expose the image file as sda1 (or sda, if you want to partition it). I don't see any benefit in telling the domU to use it as md4.
From the domU's point of view it does not matter anyway, as you are using an image as its filesystem.
Update:
Coming to thing about, it probably does not matter much what you call the block device in domU. However, assuming that you have a paravirtualized domU running Linux, you have to make sure that the xenblk kernel module is in your initrd. Without this driver, the domU will not be able to see those block devices.
This does not really make sense. Either it's not on a RAID, then it's sda4.. or it's on a RAID, then it may be md4. But not both.The /home/virtual is my sda4 -- as raid: md4.

Thanks for helping Ace!
What I have is my /dev/sda4 mounted as RAID (so it became /dev/md4).
This is a partition where I intend to store all the domU images, so if I want to add 10 or more images to the disk I can just create another .img file.
The main problem is that domU is not recognizing the disk. I've tried this:
And also this:
And this is my raid mounted:
/dev/md4 622G 31G 592G 5% /home/virtual
But in both cases domU wont find the disk and keeps giving me Kernel Panic: Unable to load VFS...
Any idea?

It should look more like this:
And you should have /dev/sda1 in your fstab for the root filesystem in the DomU. Also make sure, you dont have this when booting your DomU in your dmesg of the DomU:
It must look like this then:

We're getting closer!
Now, I guess there is another problem.
It freezes after mounting the partition.
Any idea?

first, you should downgrade the udev version or upgrade the xen-kernel as suggested in the log you posted. Check for a newer kernel right here: http://forums.gentoo.org/viewtopic-t-709908.html
andylyon provides new kernels with xen-patches. I wasnt able to get every version running, but it seems a lot of other users were able to get it running.
bb
EDIT: you could try disabling local as well, but your udev issue will stay.

Maybe the tty settings in your inittab of the DomU are incorrect. Or you need one more option in your cfg-file for the DomU. Ill check this later. It too late for me now. Need some sleep.

Hi BB!
Thanks again.
I worked with the downloaded image.
Also I've noticed that my image works on SSH, but it wont show the login screen.
Look what I got in my message log file:
But this also happened on the downloaded image.
Any idea?
I just installed the domU by downloading this files:
http://www.las.ic.unicamp.br/pub/gentoo ... .0.tar.bz2
http://www.las.ic.unicamp.br/pub/gentoo ... .0.tar.bz2
These files were used to install the dom0 box.
What may be the cause of this error?
Thank you for your help and patience.

Any idea?
I just installed the domU by downloading this files:
http://www.las.ic.unicamp.br/pub/gentoo ... .0.tar.bz2
http://www.las.ic.unicamp.br/pub/gentoo ... .0.tar.bz2
These files were used to install the dom0 box.
What may be the cause of this error?
Thank you for your help and patience.
