[OpenIndiana-discuss] Virtualbox, OI 151a8 and vboxflt problem

[Carl Brewer]

G'day,
I have a pretty happy OI151a8 server running Virtualbox 4.3.6

It's got 3 guests (2 NetBSD, one CentOS 5).  They mostly just burble 
along, except every now and then (roughly every 7-10 days) they lose 
network connectivity.  The only way I've found to get them online again 
is to shut them down, remove and re-add vboxflt (rem_drv vboxflt, reboot 
OI server, add_drv vboxflt) and restart the guests.  The host shows no 
symptoms that I've been able to find, I can ssh into it just fine.  It's 
just the guests that fall off the network.

I'm not sure how best to go about fixing this, as VB isn't really 
supported on OI, we're just kinda lucky it runs.

Any suggestions?  Should I file a bug report with OI/Illuminos?  Or 
Oracle?(!).

Is anyone else seeing this?

Thanks

Carl
