Hi folks,

I have successfully migrated from a Debian Etch dom0 running Xen 3.0.3 (installed using apt-get) to a Slackware64 dom0 running Xen 4.0.0 (all installed from source). It went a lot better than I expected. But I have a couple of issues to resolve. I'll try to fix them in order of importance so here's the first:

I have a Debian Etch domU which is unable to mount more than one virtual disk. It has a root disk, a swap disk and a filesystem that I share from this domU to my network using Samba. At boot it can mount root partition (/dev/xvda1) but it's not able to mount swap (/dev/xvda2) or the FS I share to the network.


This is the boot message:


INIT: version 2.86 booting

This is the conf file for this particular domU:


kernel  = '/boot/vmlinuz-2.6.31.13-20100501'
memory  = '128'
root    = '/dev/xvda1 ro'
disk    = [ 'phy:xenvol/sqlserver-disk,xvda1,w', 'phy:xenvol/sqlserver-swap,xvda2,w', 'phy:stuff/files,xvda3,w' ]
name    = 'sqlserver'
vif  = [ 'ip=192.168.2.203,bridge=eth0' ]
>
on_reboot   = 'restart'
on_crash    = 'restart'
#extra = 'console=hvc0 xencons=tty'
extra       = 'console=hvc0 xencons=tty'


I have other Slackware domU's but they do not suffer this problem. In the conf file I changed xvda# to sda# back and forth with no luck. I'm able to mount the filesystem in dom0 and I can create files/directories on it without any problem.

What I'm missing?? Any hint will be very much appreciated.

Thanks in advance.
