Re: [libvirt] Passing -no-kvm-irqchip to KVM/QEMU guests

Dear libvirt,

Is there a way to tell a KVM/QEMU guest managed by libvirt to start with the "-no-kvm-irqchip" argument?

I have some FreeBSD 7 guests with timing issues, and if I try to start the VMs manually with -no-kvm-irqchip, the timing issues go away (the only known workaround right now).

However, if the guest is managed by libvirt, I have found no way to pass this command line option.

I'm running libvirt 0.6.4 on Ubuntu 9.04

As a hack, you can point the XML file to a wrapper script instead of the KVM binary, where the script would contain e.g.: #!/bin/sh exec /usr/bin/kvm "$@" -no-kvm-irqchip -jim
