Summary: Exporting LVM device to domU Product: Xen Version: 3.0.2 Platform: x86 OS/Version: Linux-2.6 Status: NEW Severity: normal Priority: P2 Component: Guest-OS AssignedTo: xen-...@lists.xensource.com ReportedBy: max...@benefit-tech.co.il

Hi there,

I'm using xen-3.0.2.2-86.1_rhel4.1 on a Redhat AS 4 update 1 for i386. When I create a new domU with the following conf file, everything is ok: ##BEGINNING## kernel = "/boot/vmlinuz-2.6.16-xen3_86.1_rhel4.1" ramdisk = "/boot/initrd-2.6.16-xen3_86.1_rhel4.1.img" builder='linux' memory = 1024 name = "myvm" vcpus = 8 vif = [ 'mac=00:16:3E:6C:54:FE, bridge=xenbr0' ] disk = [ 'phy:vg02/lvol0,sda7,w' ] disk = [ 'phy:sda6,sda6,w' ] dhcp="dhcp" hostname= "myvm" root = "/dev/sda6 rw" extra = "4" ##END##

However, when I change the order of the two "disk" statements ([ 'phy:sda6,sda6,w' ] first and [ 'phy:vg02/lvol0,sda7,rw' ] second), and try to create the new vm (xm create -c myvmconf), I get the usual output with this error at the end: ##BEGINNING## Loading ext3.ko module Creating root device Mounting root filesystem mount: error 6 mounting ext3 mount: error 2 mounting none Switching to new root switchroot: mount failed: 22 umount /initrd/dev failed: 2 Kernel panic - not syncing: Attempted to kill init! ##END##

Any ideas why it's happening? Maxim.
