20090119 - Oracle VM more thoughts

Not yet convinced about Xen. (Oracle VM).

No AD Integration for Usernames
No "BIOS" screen to configure boot orders
No Guest "Tools"
No Memory Page Sharing
No thinly provisioned disks
No performance stats
No Hot Migration tools
Realtek rather than Intel NIC driver
Doesn't "grab" the mouse pointer. Hence have two mouse pointers (not synchronous).
Only 1 person can connect to VNC at a time

What I do like about it is:

32-way VMs (even on a 8 way server!)

Also, PVMs have a few oddities:
No GRUB (even though there is a grub config file)
sttys rows doesn't work
dmidecode doesn't work
/dev/xvda device rather than /dev/hda


My First Para VM.
