OS: Fedora Core 3

Kernel: 2.6.11

Hmm maybe this partly was my wrong doing lol.

After creating all the image files including base+devtools.

I forgot to umount the image files and started creating the virtual servers (domU).

Then on the host itself, i did a umount on that partition and the virtual servers started posting alotof ext3-fs errors.

So not sure if this is a kernel bug within the domU kernel or maybe something that i should not have done lol.

Thanks,

rudy
