Hello,

I just tried running Xen 4.0.0-rc5 (64bit) with latest xen/stable 2.6.32.9 dom0 
kernel (64bit aswell).
System boots up fine, and I'm able to run PV guests using phy: disk backend 
(lvm volumes).

I tried using tap:aio: file-based storage with virt-manager for a PV guest. 
It seems it doesn't really work, the guest waits for a long time 
initializing disk drivers/devices, and then complains about not having any 
disks.

$ xm list -l testfoo
..
    (device
        (tap
            (protocol x86_64-abi)
            (uuid f7723325-9ff4-96f7-0808-9ec05a00a4b8)
            (bootable 1)
            (dev xvda:disk)
            (uname tap:aio:/var/lib/libvirt/images/testfoo.img)
            (mode w)
            (backend 0)
            (VDI )
        )
    )

Am I supposed to have that 'uname' there? This could be a problem with 
virt-manager or libvirt,
so I'll try with plain normal /etc/xen/ cfgfiles next..

Also it seems pvfb uses the broken 'relative' mouse instead of 'absolute', 
any ideas why that happens?
