FreeBSD freeze during boot when running in Qemu KVM on AMD and Intel

Bug Description

I'm running latest kernel on 11.04 and just installed the kvm tools.

After creating a virtual machine using the gui and starting it the vm freezes almost instantly, the bootloader timer of freebsd either freezes directly or ticks down no further than 7.

This seems to be the same bug as reported on this post in a mailing list:

where also a fix is suggested:
with more details in:

With KVM disabled FreeBSD does boot, but my machine should be capable of running KVM and FreeBSD should be able to run as DomU

As a workaround, really annoying one thou, you can start the freebsd guest and connect to the console with vnc. Start hammering the enter key before the countdown screen, so you can get an enter keypress in instantly as that screen shows up. Then the guest will continue booting.

There are patches in the kvm git kernel that fixes this as described in the link from original post.

This bug and 780657 are likely due to the same issue.

In that report you can disable to FreeBSD boot menu (or alternatively replace the bios in KVM) as a work around also.

As reported by: Bjoern Connolly (pobox)
beastie_disable="YES" in /boot/loader.conf solves the problem of booting FreeBSD.

Hey Guys,

I ran into the same bug as Gijs Peskens did. My FreeBSD virtual maschines are freezing at the boot menu if the beastie logo is enabled and if I use a qemu version from saucy (1.5.0+dfsg-3ubuntu5.3) or trusty (1.7.0+dfsg-3ubuntu5). Version 1.2.0+noroms-0ubuntu2.12.10.6 and 1.0+noroms-0ubuntu14.13 from quantal/precise are working fine.

I've no control of the virtual maschines, only the host system so I can't modify the /boot/loader.conf. Any thoughts on how I can fix this issue on the server side?

Let my know if you need any logs or more information-

Forgot to mention:

I've tested this on two different CPUs:
model name : Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz
model name : Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz

so this isn't only AMD related.

summary: - FreeBSD freeze when running in Qemu KVM on AMD
+ FreeBSD freeze during boot when running in Qemu KVM on AMD and Intel


could anybody offer me some ideas for debugging. Or has anybody some thoughts about this issue?

Tested this with vanilla Qemu 1.7.1 and 1.5. I have no issues with these vanilla versions. the bug seems to be ubuntu related

This happens also with vanilla kernel, so its more an qemu-kvm bug then kernel related

affects: linux (Ubuntu) → qemu-kvm (Ubuntu)

Please give us a url for an iso we can use to install, and the install options you are using. I'll see if I can reproduce with 14.04's qemu and with upstream git HEAD.

Hi Serge,

You should be able to reproduce this with any iso from

Let me know if you need more information.

I still was not able to reproduce this, using virt-manager on trusty and using mostly the defaults.

In comment #9 you said "with vanilla kernel" - can you please list the exact kernel versions you've tried (and which qemu versions you tried with them, including whether they were hand-built from git or packages from Ubuntu)

I tried 3.2.0-27-generic and 3.11.0-18-generic from the precise repos. Also a vanilla 3.10.18 and 3.10.28 based on the 3.2.0-27-generic config file. I tried these ubuntu packages for qemu: saucy (1.5.0+dfsg-3ubuntu5.3) and trusty (1.7.0+dfsg-3ubuntu5). Also the plain qemu from

I debugged this issue further. I got the freebsd Images from a friend. They are modified with MSFBSD( Plain FreeBSD is also working fine (sorry for the wrong information in the above messages). I notifed the responsible developer Martin Matuška and waiting for his reply.
