I'm trying to isntall Xen on ubuntu 12.04 LTS for the first time (running on blade server, 8GB ram, without the naughty iscsi controller, running LSISAS1064E)
I've followed the official ubuntu instructions and got the infamous
"(XEN) Not enough memory to relocate the dom0 Kernel image" error.
I tried building the kernel with dom0 support manually (by following the Xen's Mainline Linux Kernel Configs) as suggested in the ubuntu forums but I keep receiving the error even with my kernels (needless to say the ubuntu OS boots fine with them).
I've tried the latest stable kernel (3.7.4) using both ubuntu's kernel and manual build from the official sources as well as 3.8.0-rc4 (from kernel.org)
I've tried setting the dom0 ram size in
GRUB_DEFAULT="Xen 4.1-amd64" #GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=30 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="" GRUB_CMDLINE_LINUX="rootdelay=180" GRUB_DISABLE_OS_PROBER=true GRUB_CMDLINE_LINUX="apparmor=0" GRUB_CMDLINE_XEN_DEFAULT="dom0_mem=512M"
Switched the default stack to
xl (as advised here) and just to be sure - the default bios boot option is the SAS. Yet, I still keep getting the error. I tried google-ing it but most of the answers are about the QLogic iSCSI controller.
Am I missing something or should I go back to vmaware ?
