[uml-devel] swap problem

[uml-devel] swap problem

Hi,

I'm unable to get the swap file working with uml (2.6.13-bs2).
I created a 512Mb file using dd and formatted it using 'mkswap ./swap'.
I start uml with the command:
vmlinux mem=128m ubd0d=root_fs.fc4 ubd1d=swap
eth0=tuntap,,,10.10.20.6<http://10.10.20.6>
I've got 8 devices under /dev/ubd and only /dev/ubd/0 seems to be working
and used for the root partition.
I see the following messages during the boot:
.
.
[42949373.340000] ubda: unknown partition table
[42949373.340000] ubdb: unknown partition table
.
.
Enabling swap space: swapon: /dev/ubd/1: No such device or address [FAILED]

Any idea?

Thanks,

That's normal, as there's no partition table on /dev/ubd0 (or let's call 
it /dev/ubda, it's the same thing). You normally mount /dev/hda1, 
not /dev/hda, but mount /dev/ubda, not /dev/ubda1.

Check the minor number. It should be 16, but there are around root_fs with 
number 1 (which was correct when UBD didn't support partitions). This would 
explain everything in your setup.
