[Xen-users] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(3, 1)
i''m currently trying to install xen 2.0.6 on debian sarge/x86. i take
package from "deb http://www.option-c.com/debian unstable main"

i boot xen dom0 with the following in grub menu.lst

I think you should add a root=/dev/hda1 to your kernel stanza in menu.lst. Mine is like this: title Xen 2 - Kernel 2.6 root (hd0,0) kernel /xen.gz dom0_mem=131072 root=/dev/hda3 ro console=tty0 module /vmlinuz-2.6-xen0 root=/dev/hda3 ro console=tty0 savedefault boot I don''t understand the logic of repeating the root and console directives, but it works! :) Marcus. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(3, 1)
Julien, Looking at your menu list, I''m curious about this line: module /initrd.img-2.6.11-ocxen0 Did you create an initrd.img by hand? That kernel is minimal, and was designed to boot without need for an initrd (as long as the hardware which contains your root device is supported, which it appears to be). You might want to try removing that line. If that doesn''t help, please post a dmesg from a boot for a non-xen kernel -Yvette On 7/4/05, Julien TOUCHE <julien.touche@lycos.com> wrote:> > i''m currently trying to install xen 2.0.6 on debian sarge/x86. i take > package from "deb http://www.option-c.com/debian unstable main" > + tools > > i boot xen dom0 with the following in grub menu.lst > > title Xen 2.0 > root (hd0,1) > kernel /xen.gz dom0_mem=65536 noacpi max_loop=32 com1=19200,8n1 > module /xen-linux-2.6.11-ocxen0 root=/dev/hda1 ro > console=ttyS0,19200 console=tty0 > module /initrd.img-2.6.11-ocxen0 > > ==> Booting ''Xen 2.0'' > > root (hd0,1) > Filesystem type is ext2fs, partition type 0x83 > kernel /xen.gz dom0_mem=65536 noacpi max_loop=32 com1=19200,8n1 > [Multiboot-elf, <0x100000:0x3f070:0x35f90>, shtab=0x175078, > entry=0x100000] > module /xen-linux-2.6.11-ocxen0 root=/dev/hda5 ro > console=ttyS0,19200 > console=tty0 > [Multiboot-module @ 0x176000, 0x3fc808 bytes] > module /initrd.img-2.6.11-ocxen0 > [Multiboot-module @ 0x573000, 0xfa000 bytes] > > __ __ ____ ___ __ > \ \/ /___ _ __ |___ \ / _ \ / /_ > \ // _ \ ''_ \ __) || | | | ''_ \ > / \ __/ | | | / __/ | |_| | (_) | > /_/\_\___|_| |_| |_____(_)___(_)___/ > > http://www.cl.cam.ac.uk/netos/xen > University of Cambridge Computer Laboratory > > Xen version 2.0.6 (root@[unknown]) (gcc version 3.3.5 (Debian > 1:3.3.5-13)) Mon > Jun 13 23:39:47 UTC 2005 > Latest ChangeSet: information unavailable > > (XEN) Physical RAM map: > (XEN) 0000000000000000 - 00000000000a0000 (usable) > (XEN) 00000000000f0000 - 0000000000100000 (reserved) > (XEN) 0000000000100000 - 0000000010000000 (usable) > (XEN) 00000000ffff0000 - 0000000100000000 (reserved) > (XEN) System RAM: 255MB (261760kB) > (XEN) Xen heap: 10MB (10788kB) > (XEN) CPU0: Before vendor init, caps: 0183f9ff 00000000 00000000, vendor = 0 > (XEN) CPU caps: 0183f9ff 00000000 00000000 00000000 > (XEN) Using scheduler: Borrowed Virtual Time (bvt) > (XEN) Initializing CPU#0 > (XEN) Detected 300.689 MHz processor. > (XEN) Local APIC disabled by BIOS -- reenabling. > (XEN) Found and enabled local APIC! > (XEN) CPU0: Before vendor init, caps: 0183fbff 00000000 00000000, vendor = 0 > (XEN) CPU caps: 0183fbff 00000000 00000000 00000000 > (XEN) CPU0 booted > (XEN) SMP motherboard not detected. > (XEN) enabled ExtINT on CPU#0 > (XEN) ESR value before enabling vector: 00000000 > (XEN) ESR value after enabling vector: 00000000 > (XEN) Using local APIC timer interrupts. > (XEN) Calibrating APIC timer for CPU0... > (XEN) .....
