[ovirt-users] Crash Debugging VDSM Hook

Hi All, While debugging some Qemu 6 issue I was requested to remove the error_policy from the libvirt xml. See https://bugzilla.redhat.com/show_bug.cgi?id=1999051#c12 Now to have this working I just wrote some small python hook for VDSM which adjusts the XML before startup. Just added the file in /usr/libexec/vdsm/hooks/before_vm_start: # cat 40_crashtest #!/usr/libexec/platform-python import os import hooking class CrashTestHook(object):     def __init__(self):         super(CrashTestHook, self).__init__()         self.config = {}         self.domxml = hooking.read_domxml()     def save(self):         hooking.write_domxml(self.domxml)     def set_error_policy(self):         drivers = self.domxml.getElementsByTagName('driver')         for driver in drivers:             policy = driver.getAttribute('error_policy')             if policy == 'stop':                 driver.removeAttribute('error_policy')     def main(self):         self.set_error_policy()         self.save() if __name__ == "__main__":     CrashTestHook().main() # vim: expandtab tabstop=4 shiftwidth=4 Might be usefull if somebody else needs the same thing :) Jean-Louis
