Re: Embedded FreeBSD on a five-core RISC-V processor using LLVM
I believe a few will be interested in OpenBSD on RISC-V hardware. This is the first time, a BSD is booting on RISC-V hardware. Looking forward to get OpenBSD on RISC-V hardware. So, it might be interesting to look at this talk and associated tracks. OpenBSD on Open Source CPUs (like Shakti RISC-V) would make a great firewall. Thanks.

Embedded FreeBSD on a five-core RISC-V processor using LLVM
Hi, This talk https://fosdem.org/2019/schedule/event/testing_freebsd_risc_v5/ is being presented at 1130 UTC Sat Feb 2nd. You can view via live streaming video. They talk about FreeBSD bring up on the SiFive FU540, RISC-V board. The BSD track is at https://fosdem.org/2019/schedule/track/bsd/ The RISC-V track is at https://fosdem.org/2019/schedule/track/risc_v/ Thanks. Regards Dinesh

VMD from Network!
Hi All, Please help me to setup my VMM/VMD to install per PXE. Is it posible if I have just MAC from VMM Client. The other staff (PXE Server) is ready to install my VM. Many Thx. Oleg
VMs loosing network connectivity for a few minutes on a daily basis
Hello,
I am testing VMM/VMD on OpenBSD 6.4 with OpenBSD 6.4 virtual machines but
noticed that maybe around 2 times per day the VM loose their network
connectivity for a short amount of time of around 2-3 minutes. I currently have
3 OpenBSD VM with very light load on them and it happens to all of them.
The network connectivity recovers on its own or if I login through the console
to the VM and initiate for example a ping to the outside. The host/hypervisor
itself never looses connectivity.
Now I presume there is either an issue with my network setup or maybe a bug but
I would rather think it has to do with my network setup. My network setup on
the OpenBSD host itself consists of two physical network devices (bnx0 + bnx1)
which I have bundled in a trunk (trunk0) in failover mode. Then on top of my
trunk I have two VLAN interfaces (vlan2 and vlan6). vlan2 is my private network
and vlan6 is my public facing network (internet). Then finally I have a bridge
interface (bridge6) with my vlan6 interface inside where my VM connect to as
they are directly available on the internet.
So the whole chain of network interfaces from host to VM looks like this:
[bnx0+bnx1]-[trunk0]-[vlan6]-[bridge6]-[tap0]-[vio0]
My /etc/vm.conf looks like this:
switch "uplink_vlan6" {
interface bridge6
}
vm "obsd1vm" {
memory 2G
disk "/var/vmm/obsd1vm.qcow2"
interface {
switch "uplink_vlan6"
lladdr fe:e1:bb:03:01:01
}
}
My /etc/hostname.* files look like this:
/etc/hostname.bnx0
up
/etc/hostname.bnx1
up
/etc/hostname.trunk0
trunkproto failover trunkport bnx0 trunkport bnx1 up
/etc/hostname.vlan2
inet 192.168.1.56 255.255.255.0 192.168.1.255 vnetid 2 parent trunk0
description "private" up
/etc/hostname.vlan6
inet xxx.xxx.xxx.xxx 255.255.255.0 xxx.xxx.xxx.255 vnetid 6 parent trunk0
description "public" up
/etc/hostname.bridge6
add vlan6
up
The hardware switch behind the host is a Cisco switch and the two ports
connected to the two hardware NICS of the server have both the following config:
interface Eth101/1/9
switchport mode trunk
switchport trunk native vlan 99
switchport trunk allowed vlan 2,6
Finally below is the output of ifconfig:

Last note, the host and VMs are all patched up to 013_unveil.
I hope I could provide here all the relevant details, if there is anything else
I should add I would be happy to provide with more info.
Best regards,

I think carp will delay itself until the sync is done, so it will not try to take over even if it has lower advskew than the other, until the sync is complete. -- May the most significant bit of your life be positive.

sound short stops in mpv when doing firefox stuff
Hello, I use mpv with a network stream (radio) and in the same time I use firefox for browsing. There is some audible sound short stop each time I open a new tab in firefox and sometimes when in change tabs. This it doesn't happen if I listen to that stream in the firefox browser, no matter how many tabs I open. I use the most recent snapshot/amd64. I tried to adjust cache for mpv but it does not matter. Vlc is playing fine, as cvlc terminal app. I want to stick with mpv for the moment, so if anyone is an expert in fine tuning it, please drop here a hint. Even if it cannot be fixed for the moment, Thank you.
