Ubuntu 12.04 VM gives error: *ILLEGAL INSTRUCTION* running as a host in
Xen XCP 1.5.
Seems the issue is with the newer AMD 6200 series processors (CPU's).
We are running AMD 6274 chips, and had to append this
*"cpuid_mask_cpu=fam_10_rev_c*"
to the extlinux.conf file:
label xe
# XCP
kernel mboot.c32
append /boot/xen.gz *cpuid_mask_cpu=fam_10_rev_c* dom0_mem=752M
lowmem_emergency
_pool=1M crashkernel=64M@32M console= vga=mode-0x0311 ---
/boot/vmlinuz-2.6-xen
root=LABEL=root-bptvgzah ro xencons=hvc console=hvc0 console=tty0 quiet
vga=785
splash --- /boot/initrd-2.6-xen.img
Reducing the instruction set to an older K10 operation architecture
fixed the issue.
This now allows Ubuntu 12.04 to function correctly as a VM in Xen XCP 1.5.
So... my question is this... seems Citrix has fixed this issue with the
newest release of Xen Server 6.0.2, when will this be included in Xen
XCP? We do NOT use Citrix Xen Server at all, instead, we use Xen XCP 1.5.
