Re: using linux as domU. --- done!!!

First, I successfully got Ubuntu domU using an image.

Second, I'm having trouble creating a file system to untar a file system.

Also, when installing a linux domu, you can simply tar up and extract an existing filesystem of a working desktop/server of any distro to either a partition or file image. The problem for most BSDers is they have no existing, or want for an existing system.

In attempting to create a file system on a vnode under NetBSD-4.99 with
newfs_ext2fs it reports back that when opening for write it is busy.
Can someone give me a hint of what I am doing wrong?

It seems that NetBSD-4.0 had a package to work with ext2fs while 4.99 has
it as part of the system. =====

newfs_ext2fs: /dev/vnd6a: open for write: Device busy

If you bother to handcraft a basic linux image for bootstrapping debian etc, it's worthwhile keeping a copy for creating custom installs later on. Also consider backing up your fresh distro installs as these can be used to roll out additional domu later on. Every now and then I boot into my backup images and update them so I don't have to worry when rolling out.

Hopefully some of that is useful.
