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 *********** sudo xm create modifiedxmconfig.cfg -c Password: Using config file "./modifiedxmconfig.cfg".
