Re: libvirt 1.3.2 - can't start libvirtd service

I had same problem. Downgrade to libvirt-1.3.1-1 works fine for me.
I did downgrade libvirt package, systemctl daemon-reload then restart libvirtd.service.

Re: libvirt 1.3.2 - can't start libvirtd service

Issue further defined in  FS#48440
I pushed my PKGBUILD modifications to github
Rebuilding package successfully resolves stated issues on my end.

Edit to add:

Unfortuntly this trick with Type=notify did not help.
Tryed on 4.4.1 kernel

If you had libvirtd enabled, also run

systemctl reenable libvirtd.service

This will retarget the symlinks to your modified location if using that approach.  Note this stopgap fix should be purged from system once resolved to avoid floating config file preventing Arch updates, i.e.

rm /etc/systemd/system/libvirtd.service

Looks like the fixed version is out.

Re: libvirt 1.3.2 - can't start libvirtd service

AFAICT there are actually 2 issues here:
* The first only applies if you're running kernel 4.4.1-2-ARCH. (or any 4.4 kernel, didn't narrow it down).The kernel crashes if you try to start a VM. If you wait long enough, you get a "hanging_task" message, but then it's already too late.
It's a symptom, not the cause. Fix it by downgrading the kernel to 4.3 (http://ala.seblu.net/packages/l/linux/l … pkg.tar.xz)

Does anyone have solution for this issue beside downgrading kernel ?

My old VM which created before kernel 4.4 is fine, I can start them without hanging my system.

But sometimes (more than often) I start VM created after 4.4, my system isn't responding anymore and I have to hard reset it.

If I have to create new topic for this question, please tell me. Thanks in advance.

Have you tried to upgrade to the latest kernel 4.4.5-1?
They have implemented a fix for those deadlocks in 4.4.4.

Same here hoanguyen2708
So far my only clean workaround was switching to the LTS kernel. That works fine but it's just a workaround. A new thread might be better than this one though as the immediate issue here is solved.

The ix7 ... Will try right away as I have a new host to setup anyway.

I can confirm that the last kernel update solves that problem as well.
New host and an old one where i could reproduce a hang easily were updated and all is fine there.

Thx ix7

Yup. I can't get it to hang anymore, no matter how many VMs I fire up.
