QEMU update. reboot?

[BelCloud]

Hello

I've seen some vulnerabilities in qemu-kvm, that were recently patched.
For ex, CVE-2017-7980

In the redhat announcements, i saw they require a stop of all VMs for the update to take effect.

Do we need to follow the same procedure when proxmox updates the qemu? Or it's patched in another way.

Thank you

Usually a live migration will resolve this without the need to stop or start the VM.
