general:linux:debian_jessie_grub-xen-host
Running PV grub from within domU
Tested with Debian Jessie in both dom0 and domU
With information from here
http://www.hellion.org.uk/blog/posts/debian-pvgrub2/
With Jessie, install grub-xen-host in your domain 0 and grub-xen in your PV guests then in your guest configuration, depending on whether you want a 32- or 64-bit PV guest write either:
kernel = "/usr/lib/grub-xen/grub-i386-xen.bin" or kernel = "/usr/lib/grub-xen/grub-x86_64-xen.bin"
(instead of bootloader = … or other kernel = …, also omit ramdisk = … and any command line related stuff (e.g. root = …, extra = …, cmdline = … ) and your guests will boot using Grub 2, much like on native.
Seems to be unstable with i386
bigbang:/etc/xen# xl create -c /etc/xen/pbx Parsing config from /etc/xen/pbx libxl: error: libxl_dom.c:35:libxl__domain_type: unable to get domain type for domid=137 Unable to attach console libxl: error: libxl_exec.c:118:libxl_report_child_exitstatus: console child [0] exited with error status 1 bigbang:/etc/xen# xl create -c /etc/xen/pbx Parsing config from /etc/xen/pbx libxl: error: libxl_dom.c:35:libxl__domain_type: unable to get domain type for domid=138 Unable to attach console libxl: error: libxl_exec.c:118:libxl_report_child_exitstatus: console child [0] exited with error status 1 bigbang:/etc/xen# xl create -c /etc/xen/pbx
And suddenly it works..
A workaround for this seems to be removing /boot/xen/* as then it is not possible to chainload the domU grub and the grub that was loaded from dom0 reads grub.cfg and finishes the boot (now working all the time..)
A drawback is then of course that you are stuck with the functionality that resides in the dom0 grub version
