Bug ID: 292961
Summary: Microsoft SQL Server inside a Linux VM on bhyve host
Product: Base System
Version: 15.0-RELEASE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bhyve
Assignee: [email protected]
Reporter: [email protected]
For a testing project I wanted to deploy mssql Server inside a Linux VM. I am
proficient in using docker on Linux. First, I tried to get the image to run
inside my Kali Linux VM - it started, did not produce any errors, but the
process kept running at 100% CPU. The same happened on another fresh Debian 13
VM.
This was on my FreeBSD 15.0-RELEASE host (p2) with a AMD Ryzen 7 3700X 8-Core
Processor and 64GB of ECC-RAM. I was suspicious and tried another vm on my
small server, FreeBSD 15.0-RELEASE (p2) with a Intel(R) Atom(TM) CPU C3558 @
2.20GHz (2200.21-MHz K8-class CPU) and 32GB ECC-RAM. The same behaviour. It did
not have an issue when using a Linux notebook without virtualization, so I dug
deeper.
Then, I installed Debian 13 on my oldish HP Z440 Workstation with a Intel(R)
Xeon(R) CPU E5-1630 v4 @ 3.70GHz (3691.66-MHz K8-class CPU) and 32GB ECC-RAM. I
used KVM to install a virtual machine (Debian 13) and ran mssql server inside
that VM - no problem, even with a docker volume it worked as it should.
I then installed on the same HP Z440 Workstation on a different disk a fresh
version of FreeBSD 15.0-RELEASE (p2) and with vm-bhyve I created a Debian Linux
VM (Debian 13). I installed the exact same packages as in the Debian 13 VM from
the Z440 Linux host. Here, the mssql process again went to 100% CPU and it did
not work. On a second VM, I tried the same, but with nvme as storage and e1000
as network interface, however, this did not change the behaviour.
