有名OSSが主語デカいコマンド名を取ったせいでコマンド名衝突するのたまにあって困る。最近はvmっていうコマンドを見た(FreeBSDでbhyveのマネージャが使ってる)。コマンドにもfull qualified nameを用意して、ユーザがこれをエイリアスするという世界観だと便利そう。

FreeBSD, v13.2, is out. Lots of package upgrades including to OpenSSH 9.2p1, OpenSSL 1.1.1t, and OpenZFS 2.1.9. New features include upgrading the bhyve hypervisor to now support more than 16 virtual CPUs in a guest, a WireGuard VPN driver, netlink for network config and more.

うちのFreeBSDマシン、13.3にアップデートしたところbhyveでのゲストOSが動かなくなってしまった。古いAMDのCPUを使っているためなのかなあ。そういえばRHEL9もCPUの制限が厳しくなったようなので、そろそろ新調しないといけない時期になってしまった。

bhyve: Add PL011 UART emulation

This will be use for arm64 guests, instead of the existing ns16550 UART
model.

bhyve: Provide optional libfdt linking

The arm64 port currently does not support ACPI, it instead builds up an
FDT which is exported to the guest. This mechanism will not ...

I'm getting a kernel up and running on bhyve, because I need a working debugger and not having to restart my machine every time it panics.

Jessica Clarke via markj@ on usr.sbin/bhyve (4dfa329f48):

bhyve: Extend mevent to support updating timers

This will be used by a new PL031 implementation to provide an RTC for
arm64 guests.

PCI devices.

The bloody wifi thing. I run it on my desktop and that's fine. I also run it on my laptop, and wifi is a pain in the ass, having to run linux in a bhyve vm (wifibox, which breaks virtualbox which is handy in a laptop).

segment) and bhyve, in preparation ...

Sheridan Computers Two hypervisors in parallel? That won't work… but it makes me wonder if it's possible to migrate the wifibox VM to Vbox, and have it start at boot? (And suspend and resume correctly.) Otherwise you'll need to find a Vbox-like GUI for bhyve, not sure if there is one.
