I would like to register a binary handler for byte compiled python code.
lenny2:/# mount -t binfmt_misc none /proc/sys/fs/binfmt_misc
mount: unknown filesystem type 'binfmt_misc'
lenny2:/# mount
simfs on / type simfs (rw)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=755)
proc on /proc type proc (rw,nosuid,nodev,noexec)
sysfs on /sys type sysfs (rw,nosuid,nodev,noexec)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
devpts on /dev/pts type devpts (rw,nosuid,noexec,gid=5,mode=620)
On hardware node I'm running Debian GNU/Linux 5.0.3 with kernel 2.6.26-2-openvz-amd64 and vzctl 3.0.23-8
On a proxmox PVE 1.1 with kernel 2.6.24-2-pve with vzctl 3.0.23-1pve1 I get same error.
I have tried loading binfmt_misc and mounting binfmt_misc on HN and restarted VE without luck.
When googling for OpenVZ and binfmt_misc I can see that other people have fs type binfmt_misc mounted inside VE.
Is binfmt_misc handler interface supported inside VE's?
Is it just a capability setting?
Am I running kernels which are missing a patch?
I need a recent kernel on HN because of RAID driver

Dear Peter,
I'm terribly sorry for that big delay.
There is no trick at all.
binfmt_misc can be mounted with RHEL5 based kernels
(look at fs/binfmt_misc.c - the part under #ifdef CONFIG_VE).
Please use that kernels if you have a chance.
Unfortunately, 2.6.26 kernels don't have such a virtualization trick so I would recommend you to file a bug (mark it as a feature request for example).
Thank you.
