Subject: Does the HV_VMBUS build/install disable/break certain operating fe=
atures?
After installing a kernel with Hyper-V support (HV_VMBUS) certain functions=
are either disabled or broken. If I re-install a GENERIC kernel, however, =
everything works again. Any suggestions?
After booting with Hyper-V support (HV_VMBUS):
Not working:
1) Mouse support is disabled or broken (this should continue to be emu=
lated via Hyper-V)
2) Keyboard reverts to dumb terminal mode (e.g., arrow keys no longer =
work and Vt102 encoded char sequences appear after depressing the arrow key=
s)
3) X-windows doesn't launch (i.e., PC-BSD desktop disabled or broken),=
VGA driver may be disabled or broken (emulated in Hyper-V with a GENERIC k=
ernel)
Working:
1) Legacy network driver (emulated)
2) Netvsc (Hyper-v) network driver (haven't tried Jason's last code dr=
op for storage devices)
3) Hyper-v utilities
4) IDE drives (emulated in Hyper-V)
5) File system
My installation includes a full release of 8.2 with desktop support (PC-BSD=
8.2). I reviewed the Hyper-V (HV_VMBUS) makefile and it has an "include" f=
or GENERIC (i.e., the GENERIC configuration should be included in the HV_VM=
BUS "make"). So the only differences appear to be the options to disable ad=
aptive mutexes and RW locks. The following sections in the are missing in t=
he HV_VMBUS boot-up trace, but appear in the GENERIC trace:
