Installed on a Vista 32 system, AMD dual core
Installed on a system with 2.2.4. Installation went OK but the registration details seem to have been lost since it now comes up with nagware to register with Sun.
NetBSD 5 still doesn't boot.
I had a 2.2.x VM with no hard disk (net boot only) and it wouldn't run, though recreating it worked OK. I need to redo this experiment: looked like a problem enumerating the console?
gPXE is still very very slow when pulling images over HTTP. tftp seems OK, something odd here but not clear what.
I had a VM hang during initialisation. Couldn't kill it: had to reboot.
The 'Windows' key stopped working to pop up the menu after install. Still worked to cycle app windows though. Came back again after a reboot.
I do like the new mini-menubar.
Existing Xubuntu with 2.2.x guest additions seems to work fine, subjectively seems faster but I might be imagining it.
