If you have the version of pygrub out of Xen 4.0.1,

1) You run the version of the kernel distributed by Ubuntu(thanks to pv_ops)
2) I dont see how ACLs wouldnt be supported by the filesystem.
3) You have full access to the server console through /dev/hvc0
4) Distro level upgrades(as in from 10.04 to 10.10) *could* break the booting process. this is true.



The only con with using Ubuntu paravirtualised is lack of a framebuffer.

Server visualization seems very different than desktop visualization ala VirtualBox, Parallels, VMware. Already I have encountered (with Virtuozzo) that:

1) Does not boot a standard Ubuntu kernel, so is unable to run IPTables
2) Is not able to support ACL's on the filesystem
3) Unable to get to the server console - to watch the boot process, to fix sshd, etc...
4) Does not support Ubuntu distro version upgrades. Stuck at the level you start at.

I have heard that there are tools to be able to access the server console with Xen, but what about my other current points?

Which Xen providers do a good job with Ubuntu? (10.04 at present)

I would want a custom partitioning scheme, separate /boot, /, /srv, /var and so on... and ext4 for /boot, xfs for all others.

I assume with higher versions of Xen comes more capabilities, so knowing which version of Xen said provider uses would also be a search criteria I guess.
