Try
dom0_mem=2048MB
It should be enough (do not forget 'MB' )
you need to have enough memory to handle the init
process
OK, thanks, it boots now (at least on my test computer, I'll only
try next week on the prod server)
But I have another question, may be related... or not: when I
compile the kernel, I noticed that the modules directory is really
huge, compared to the original Debian directory:
du -sh /lib/modules/2.6.32.50 /lib/modules/2.6.32-5-xen-amd64
1.3G /lib/modules/2.6.32.50
96M /lib/modules/2.6.32-5-xen-amd64
After some investigation, it appears that each .ko file is
about 10 times bigger after recompilation:
ls -l lib/modules/2.6.32.50/kernel/fs/ext4/ext4.ko lib/modules/2.6.32-5-xen-amd64/kernel/fs/ext4/ext4.ko
-rw-r--r-- 1 root root 526872 Oct 3 11:21 lib/modules/2.6.32-5-xen-amd64/kernel/fs/ext4/ext4.ko
-rw-r--r-- 1 root root 6553221 Jan 4 16:31 lib/modules/2.6.32.50/kernel/fs/ext4/ext4.ko
May be this is the reason why dom0 needs so much memory in the new
version: do you have any idea of how I could fix that ?
