  --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=170409=edit
proposed fix, v2

Attaching a new patch that's slightly less dirty than the previous one.

Specifically, it does not change vtnet_is_link_up() behavior, but extends
vtnet_update_link_status() event triggering.

Specifically, if link is here and IFF_DRV_RUNNING is set, but interface was not
active, we mark it active and trigger notification. If there is no link or
IFF_DRV_RUNNING, then we consider interface down.

Also, add a call to vtnet_update_link_status() on mtu change to trigger events
as well like other if drivers usually do.

So, a pair of ifconfig vtnet0 down/up followed by ifconfig vtnet0 mtu 1496 look
like this in devd:

!system=IFNET subsystem=vtnet0 type=LINK_DOWN
!system=IFNET subsystem=vtnet0 type=LINK_UP
!system=IFNET subsystem=vtnet0 type=LINK_DOWN
!system=IFNET subsystem=vtnet0 type=LINK_UP
!system=IFNET subsystem=vtnet0 type=LINK_DOWN
!system=IFNET subsystem=vtnet0 type=LINK_UP

I'm yet to figure out how I can test link status change in bhyve so
vtnet_is_link_up() returned something other that 1.

Hi,

I suggest to follow this instruction:

https://www.freebsd.org/doc/handbook/virtualization-host-bhyve.html

If you still want to build a custom kernel, please refer to this guide:

https://www.freebsd.org/doc/handbook/kernelconfig.html

If this does not help still, please be more specific, "is not works" is
not really helpful, please post some more details on what you are doing
and exact errors you get.

Hm, it's strange that upgrade didn't work as expected, but if the logs
are gone there's nothing that could be done to debug that.

Anyway, good that it's working finally.

Re: FreeBSD/XEN Dom XAPI

You would have to get XAPI working on FreeBSD before trying to use XOA or 
XenCenter, those are specific products that only work with XenServer.

I don't know how much effort it would take to get XAPI working on FreeBSD, 
but I'm quite sure it's not a trivial task.

OTOH, there are other managers that you can probably use with FreeBSD/Xen, 
like OpenStack, OpenNebula or similar managers that are designed to work 
with the open source Xen Project toolstack (xl). Or you can also install 
libvirt and try to use virsh or any manager that has libvirt bindings.

Well, afer looking at help->about I noticed it was sayin 1.2 instead of
1.3. I thig the pkg upgrade didn't remove all old bits of the previous
version, so I removed virt-manager via "pkg delete" and reinstalled.
Now everything works as expected... :-)

BTW, it was on a 10.1-RELEASE-p26 amd64.

Cheers && Many Thanks,

luciano.

As a workaround on 10.3 and later you can use 'devctl set driver' to
mark devices for pass through post-boot rather than using the loader.conf
option.  E.g.:

# devctl set driver pci0:11:0:0 ppt

Currently there's no way to undo this, you can can 'set driver' to a
"native" driver if one exists.
