Severity: important
The DRBD resource script for Xen (/etc/xen/scripts/block-drbd) does not work
when
using the xl toolstack anymore, which is exclusively available in xen 4.2 and
later (i.e. the current Testing).
First of all, it needs the patch mentioned in [1] for basic support. However,
when
using it in conjunction with pygrub, it fails to find its boot device, whereas
this worked fine earlier.
Consider this configuration domu.cfg:
bootloader = '/usr/lib/xen-4.3/bin/pygrub'
disk = [
'drbd:web1,xvda1,w',
]
it fails with:
xl create -c /etc/xen/auto/matrix-web1.cfg
Parsing config from /etc/xen/auto/matrix-web1.cfg
libxl: error: libxl_bootloader.c:628:bootloader_finished: bootloader failed -

libxl: error: libxl_exec.c:118:libxl_report_child_exitstatus: bootloader

Traceback (most recent call last):

fd = os.open(file, os.O_RDONLY)
OSError: [Errno 2] No such file or directory: 'web1'
However, with the configuration:
kernel = "/boot/vmlinuz-3.2.0-4-amd64"
ramdisk = "/boot/initrd.img-3.2.0-4-amd64"
disk = [
'drbd:web1,xvda1,w',
]
it works fine. I guess the resource script needs a few more tweaks to work with
pygrub.
