time runs at 50% inside a vmm host

Paul de Weerd
I've just started using VMM to do some testing and found this issue:

[weerd@vm1] $ N=`awk '/^server/ {print $2}' /etc/ntpd.conf | head -1`
[weerd@vm1] $ rdate -npv ${N}; time sleep 10; rdate -npv ${N}
Fri May 12 11:41:07 CEST 2017
rdate: adjust local clock by 74.831786 seconds
    0m10.05s real     0m00.00s user     0m00.00s system
Fri May 12 11:41:27 CEST 2017
rdate: adjust local clock by 84.639531 seconds

So for every second of wall-clock time that passes on my VM, two
pass on the host (and on the internet).  Of course, ntpd is unable to
correct this kind of deviation.  Is this a misconfiguration on my end
or a bug?

Cheers,

Paul 'WEiRD' de Weerd

[weerd@pom] $ cat /etc/vm.conf
vm "vm1" {
        disable
        interface { switch "uplink" }
        disk /store/vmd/vm1.img
        memory 1G
        owner weerd
}

switch "uplink" {
        add em0
}

There is an easy way to detect this, run a loop in the guest system:

root@q71:~# while sleep 1; do date; done                                
Fri May 12 06:27:20 CEST 2017
Fri May 12 06:27:22 CEST 2017
Fri May 12 06:27:24 CEST 2017

I see it on a fully emulated amd64 qemu.  As a workaround I compile
my guest kernel with option HZ=50.

Problem is that the host clock and the guest clock a ticking
with exactly the same frequency.  Then interrupts are lost.
This has been discussed with mlarkin@, he knows more details.

I am not aware of a fix.

Thanks for your reply.  Yours and an off-list reply both pointed at
the HZ parameter.  I built a kernel with HZ=1000, and things now work
much better in the vm.

If not a fix, this is a fine workaround.

Thanks to all involved in the development of vmm, it's really useful
for testing lots of things!

Cheers,

I spoke too soon :-(

Things do work better, but the clock is still slow:

[weerd@vm1] $ rdate -npv ${N}; uptime
Fri May 12 16:50:14 CEST 2017
rdate: adjust local clock by 124.798956 seconds
 4:48PM  up 16 mins, 1 user, load averages: 0.00, 0.00, 0.00

So, in 16 minutes, the clock is 2 minutes behind.  So, a lot better,
but still falling behind.

[weerd@vm1] $ rdate -npv ${N}; time sleep 600; rdate -npv ${N}
Fri May 12 16:51:47 CEST 2017
rdate: adjust local clock by 135.359214 seconds
   10m03.01s real     0m00.00s user     0m00.00s system
Fri May 12 17:03:08 CEST 2017
rdate: adjust local clock by 213.572802 seconds

Which turns out to be almost 8 seconds per minute.
