Bug ID: 279271
Summary: Bhyve virtual machine after S3 mode - glitches or
freezes
Product: Base System
Version: 13.2-STABLE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bhyve
Assignee: virtualization@FreeBSD.org
Reporter: konstantin@ya.ru
Hello.
As a continuation of bug #278941, I decided to create a new bug report,
because... the problem is broader in nature.
# uname -a
FreeBSD home 13.2-RELEASE-p11 FreeBSD 13.2-RELEASE-p11
releng/13.2-n254665-f5ac4e174fdd MYGENERIC amd64
I work with bhyve virtual machines via vm-bhyve.
But I also tested without layers, through a clean launch from bhyve. The
problem will be reproduced the same way.
Reproducing the problem:
1) start a bhyve virtual machine with a guest from the list below.
2) enter S3 mode using the command "zzz" or "acpiconf -s 3".
3) exit S3 mode (turn on the computer).
4) we observe glitches in the virtual machine.
If you start the bhyve virtual machine and then enter and exit S3 mode using
the command “zzz” or “acpiconf -s 3”, the virtual machine begins to glitch,
some distributions freeze for a while. If you wait from a few minutes to
several hours, the problem may go away on its own.
For example:
- IP addresses are not pinged from inside the virtual machine, even 127.0.01.
- some commands stop being executed.
- even "reboot", "poweroff", "init 0" does not work;
- execution of the "fdisk -l" command freezes;
etc.
in this case, you can ping the guest from the host and even try to connect via
ssh, but the ssh connection is not completed completely.
Sometimes the problem may not be reproduced, but most of the time it is
reproduced.
For example, after several inputs and outputs from S3 mode, the problem itself
may not be reproduced both for all virtual machines and for some. Those. some
virtual machines will glitch, some will work fine after S3.

To fully understand the problem, you need to reproduce the problem yourself and
see what's happening with the virtual machine.
I tested this problem on a very large number of iso images and different Linux
distributions.
At the beginning, I assumed that the problem only affected Linux distributions,
but I was able to reproduce the problem on "DragonFly BSD 6.4.0" (FreeBSD fork)
by booting from the iso image. The virtual machine freezes tightly, and this is
even without X, a clean console.
The problem with bhyve virtual machine after "zzz" is reproduced on:
