vmm(4) on apu2c4

Thomas Huber
Hi misc,

is vmm(4) working on the PC-Engines APU2 with -release 6.4 ?
I thought I've read something like that a view months ago but can not find
any further information about which CPU-Feature is needed and how it is
named at the AMD.

This are the CPU-Specs for the APU2:
"AMD Embedded G series GX-412TC, 1 GHz quad Jaguar core with 64 bit and
AES-NI support, 32K data + 32K instruction cache per core, shared 2MB L2
cache."

Thanks!

does dmesg have a vmm0: SVM/RVI line?

The test from faq16.html, on pcengines apu2c4:

$ dmesg | egrep '(VMX/EPT|SVM/RVI)'
vmm0 at mainbus0: SVM/RVI

A little more info:

$ dmesg | grep -e apu -e vmm0 -e GX-412TC
bios0: PC Engines PC Engines apu4
cpu0: AMD GX-412TC SOC, 998.31 MHz
cpu1: AMD GX-412TC SOC, 998.26 MHz
cpu2: AMD GX-412TC SOC, 998.15 MHz
cpu3: AMD GX-412TC SOC, 998.31 MHz
vmm0 at mainbus0: SVM/RVI

Following faq16.html I got:
$ vmctl show
 ID   PID VCPUS  MAXMEM  CURMEM     TTY        OWNER NAME
  3 15040     1    1.0G    1.0M   ttyp1         root example

Then it should work. Does it not?

just found the time to update my APU2C4 to 6.4 and tried vmm and yes, it
works great.

I just want to let you know, that OpenBSD -release as guest on this
hardware (apu2c4)
is unusable slow during the installation-process (and I didn´t get further)
but alpine-linux for example works great.
Could this be because I´m conected trough ssh to the host and further via
vmctl console to the guest?

Are you using the -b option to vmctl? That seems to have a problem on AMD CPUs.

Try installing from install64.fs/.iso if that's the case.
