FreeBSD 11.0-RELEASE failing to probe virtual scsi controller on HyperV 2016

[Cory Smelosky]

Probably user error I bet.

Trying to boot FreeBSD 11 on HyperV 2016 w/ virtual hardware version 2
(UEFI works! wooo!) except it doesn't get very far.

the rtty documentation explains how to start it up.

you'll connect guest com1 to the host's /dev/nmdm?B ports, and symlink
rtty's dev entries to the host's /dev/nmdm?A ports. "?" is the name of
the vm.

Just to be sure: There was a UEFI loader in use? fbuf is only for GOP,
so if you boot with CSM, you won't see anything since there's no VGA
emulation. Only UEFI-GOP.

Yes, that was my question. Thanks Harry. I have read too quickly :)

Yes, but I don't see anything in vncviewer console. Can be a problem with 
graphics controller on my laptop (my laptop is the bhyve host)?

Am I wrong if I assume you confused the A/B hard-connected limit of two
interfaces with the possibility to create nmdmN[AB] number of nmdm(4)
devices?
Simply use nmdm1A/B, nmdm2A/B etc.
Not sure if I got the question rigth, answers from others don't go into
that direction...

I haven't had VNC problems besides keymapping. It's done twice and I
haven't found a way or a client to disable keymapping locally on a
session basis.
Have you used the "wait" option for fbuf? Did the vm start to run after
VNC connection attempt?

Hello,

Do have plans for Suspend/Resume? 
I'm really waiting for this feature.

Hello,
it depends on the features you need.


Not much, really.
Running SQL Server Express (for now) with decent performance.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=215737


I don't think the underlying network equipment will support Jumbo Frames :(

I don't think I'd need PCI passthrough (I'm fine with a disk and a 
network card).






· virtio-blk isn't virtio-win (Windows driver) compatible, guest will crash!

· virtio-net doesn't work with latest Windows drivers, which is not a
bhyve(4) problem as far as I can tell. Version 0.1.118 works, newer ones
are known to have problems on other hypervisors too.


Good to know.





· See if_bridge(4) for some limitations (all members need to have
exactly the same MTU, uplink gets checksum offloading disabled).
Generally, soft-switching capabilities ar not comparable with those of
ESXi, especially not the performace (outside netmap world).


This is a good point. :(




Other than that, it's rock solid for me
 ...

How well does it run Windows?
Would I better run W7 instead of W10 (or the other way round)?


Fine.




Should I use a dedicated disk (or disk mirror) for better speed?
Or should I use a dedicated partition on the host's disk/disk mirror?
Will a ZFS volume perform as good as a partition?


ZVOL is the best option offering great performance (depending on your
pool setup of yourse) as long as there is the PCI-passthru bug mentioned
above.


Thanks again.

According to nmdm(4) man page only two nullmodem devices can be
created: nmdm0A and nmdm0B (and only nmdm0A can be assigned to one
bhyve guest). Then, how can I access to these bhyve guests?


I use sysutils/vm-bhyve for bhyve management. Using console is a breeze:
---
% sudo vm console

Providing serial consoles to multiple bhyve guests

[C. L. Martinez]

Hi all,

 How can I use more than one serial console for several bhyve guests? According 
to nmdm(4) man page only two nullmodem devices can be created: nmdm0A and 
nmdm0B (and only nmdm0A can be assigned to one bhyve guest). Then, how can I 
access to these bhyve guests?

 I have tried to add vnc channel, but it doesn't works ..:(

Thanks.
