Xen hipervisor 4.1 Kernel Panic on Ubuntu 12.04
- by rkmax
I have a fresh Ubuntu 12.04.1 amd64 server install following this guide
I have used LVM option used all disk and make 2 LV
/dev/mapper/vg-root / (80GB)
vg-swap swap (4GB)
now i install xen with apt-get install xen-hypervisor-4.1-amd64 and config /etc/default/grub like the guide and add
GRUB_CMDLINE_XEN_DEFAULT="dom0_mem=768M"
later all this i exec update-grub and reboot. but when i try to boot with Xen 4.1-amd64 always i get a kernel panic with the message
Domain-0 allocation is too small for kernel image
my questions are:
this error is about what?
where i can grow this allocation for avoid this error?
grub.cfg
menuentry 'Ubuntu GNU/Linux, with Xen 4.1-amd64 and Linux 3.2.0-29-generic' --class ubuntu --class gnu-linux --class gnu --class os --class xen {
insmod part_gpt
insmod ext2
set root='(hd0,gpt2)'
search --no-floppy --fs-uuid --set=root 3541e241-7f39-4ebe-8d99-c5306294c266
echo 'Loading Xen 4.1-amd64 ...'
multiboot /xen-4.1-amd64.gz placeholder dom0_mem=768M
echo 'Loading Linux 3.2.0-29-generic ...'
module /vmlinuz-3.2.0-29-generic placeholder root=/dev/mapper/backup--xen-root ro rootdelay=180
echo 'Loading initial ramdisk ...'
module /initrd.img-3.2.0-29-generic
}
Note: I've followed this guide too
