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 :)
