[Xen-users] Newbie question: Unable to boot a file based VBD
Hi fellas: I am playing with xen on a centos distribution. Here is what all I''ve done 1. Created a file based VBD using dd and mkfs (section 6.2 of user manual) 2. Mounted this vbd and copied root, dev, etc, usr, bin, sbin, lib dirs and contents 3. Created empty dirs for proc, sys, home and tmp 4. Modified fstab of the mounted vbd /dev/xvda / ext3 defaults 1 1 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 LABEL=SWAP-sda2 swap swap defaults 0 0 5. Generated initrd mkinitrd /boot/initrd-2.6.18-92.1.18.el5xen-custom-6.img 2.6.18-92.1.18.el5xen --fstab /mnt/etc/fstab --omit-scsi-modules --with xenblk --preload xennet 6. Created a config file kernel = "/boot/vmlinuz-2.6.18-92.1.18.el5xen" ramdisk = "/boot/initrd-2.6.18-92.1.18.el5xen-custom-6.img" memory = 256 name = "ExampleDomain" vif = [ '''' ] disk = [ ''file:/home/admin/vm1disk,xvda,w'', ] #disk = [ ''phy:sda1,sda10,w''] root = "/dev/xvda rw" extra = ''selinux=0'' #dhcp="dhcp" 7. Stated the show with " sudo xm create modifiedxmconfig.cfg -c" And the kernel hangs at the last spot The log is attached at the end of this mail. Here are my observations about the log 1. Lots of PCI errors: Some config space errors followed by PCI support being disabled 2. Lots of ACPI errors: Mostly about not being able to acquire mutex. Hence ACPI support is disabled too. 3. I turned off SELinux after hearing too many stories 4. "xvda: unknown partition table" ?? 5. XENBUS: Device with no driver: device/vbd/51712 ?

AW: [Xen-users] Newbie question: Unable to boot a file based VBD
Hey
have you tried using: /dev/xvda1 instead of /dev/vdb or /dev/xvda?
maybe that will do the trick.

Betreff: [Xen-users] Newbie question: Unable to boot a file based VBD
Hi fellas:
I am playing with xen on a centos distribution.
Here is what all I''ve done
1. Created a file based VBD using dd and mkfs (section 6.2 of user manual)
2. Mounted this vbd and copied root, dev, etc, usr, bin, sbin, lib dirs and
contents
3. Created empty dirs for proc, sys, home and tmp
4. Modified fstab of the mounted vbd
/dev/xvda / ext3 defaults 1 1
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
LABEL=SWAP-sda2 swap swap defaults 0 0
5. Generated initrd
mkinitrd /boot/initrd-2.6.18-92.1.18.el5xen-custom-6.img 2.6.18-92.1.18.el5xen
--fstab /mnt/etc/fstab --omit-scsi-modules --with xenblk --preload xennet
6. Created a config file
kernel = "/boot/vmlinuz-2.6.18-92.1.18.el5xen"
ramdisk = "/boot/initrd-2.6.18-92.1.18.el5xen-custom-6.img"
memory = 256
name = "ExampleDomain"
vif = [ '''' ]
disk = [ ''file:/home/admin/vm1disk,xvda,w'', ]
#disk = [ ''phy:sda1,sda10,w'']
root = "/dev/xvda rw"
extra = ''selinux=0''
#dhcp="dhcp"
7. Stated the show with " sudo xm create modifiedxmconfig.cfg -c"
And the kernel hangs at the last spot
The log is attached at the end of this mail.
Here are my observations about the log
1. Lots of PCI errors: Some config space errors followed by PCI support being
disabled
2. Lots of ACPI errors: Mostly about not being able to acquire mutex.. Hence
ACPI support is disabled too.
3. I turned off SELinux after hearing too many stories
4. "xvda: unknown partition table" ??
5. XENBUS: Device with no driver: device/vbd/51712 ?
Note: I have also tried with tap:aio option with root=/dev/sda10 and I still get
same failure..
Any ideas about this will be eagarly lapped up :o)
Thanks
Manu

Including in the /etc/fstab. Maybe some hints here: http://blog.jphoude.qc.ca/2007/10/26/centos-5-xen-images-part-1/ (they use sda1 for example) Cheers, Todd -- Todd Deshane http://todddeshane.net http://runningxen.com _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I changed in /mnt/etc/fstab and generated initrd Then I copied this initrd to /mnt/boot and modified my config file to accommodate xvda1 and the new initrd. Unmounted the image from /mnt and gave it a whirl. Still same issue.. I''ll try the link. It looks promising.. Another idea.. Can I get dmesg logs for the guest kernel?
