Correct, I put much of the infrastructure in place but did not end up debugging it in to existence. Cheers On Tuesday, July 26, 2011, Sean Bruno sean...@yahoo-inc.com wrote: I assume then, that the i386 PV instance cannot do more than 1 CPU at this time? sean Started domain ref8-xen32

It's an artifact of the initialization code and how the xen domain builder configures the initial mapped memory. I've come against this and fixed this issue in the past but I guess either the domain builder has changed or the initial code has bit rotted. I can't commit so ask Colin if he can fix.

FreeBSD 8, PV i386 VNC fails?

2011-07-26 Thread Sean Bruno
Probably not doing it right. When I switched from pure HVM to PV on the i386 VMs in the cluster, VNC stopped working all together. Did I do it wrong? I've tried the following: vnc = 1 vncdisplay = 1 vncunused = 1 vncpasswd='' and vfb = [ type = vnc, vncdisplay = 1, vncunused = 1,

I think that sort of makes sense to me. That is, there would need to be a PV framebuffer driver for PV mode to use it. I guess. Someone(TM) just needs to port the driver. FBs are fairly trivial to support. Cheers Sean ___
