[libvirt-users] libvirt prepare and start hooks not callled

[Sundar Nadathur]

Hello,
   I am using RHEL 7.1 and libvirt 1.2.8. My intention is to intercept the prepare and start hooks of libvirt during VM placement to inject a virtio PCI device into the VM's domain xml.

I placed a python script with execute permissions in /etc/libvirt/hooks/qemu. In there, I opened a log file to record the arguments received:
log.write("avfd called with args: %s\n" % sys.argv)

But all I get in the log file is:
avfd called with args: ['/etc/libvirt/hooks/qemu', 'vm1', 'started', 'begin', '-']

There are no prepare or start calls. Can somebody explain what it takes to fix this?

Cheers,
Sundar
