Hi,
I am trying to check if a domain exists by using the libvirt python API "lookupbyname()". If the domain does not exist, it prints an error message on the console saying "Domain not found".
I need the errors or logs only in syslog. I have tried redirecting stderr and stdout. But, it doesn't have any effect. I have also tried playing around with the libvirt logging settings described in https://libvirt.org/logging.html . No effect again. "stdio_handler" flag in /etc/libvirt/qemu.conf is set to "file" as well.
Following is my test code:
import os, sys
import libvirt
conn = libvirt.open('qemu:///system')
# Find the application in the virsh domain
try:
sys.stdout = open(os.devnull, "w")
sys.stderr = open(os.devnull, "w")
dom = conn.lookupByName('abcd')
sys.stdout = sys.__stdout__
sys.stderr = sys.__stderr__
except Exception as e:
syslog.syslog (syslog.LOG_ERR, 'Could not find the domain. ERROR: %s.' % (e))
sys.stdout = sys.__stdout__
sys.stderr = sys.__stderr__Output:
$ python test.py
libvirt: QEMU Driver error : Domain not found: no domain with matching name 'abcd'
$Is there a way to avoid this console print?
Regards,
Swaroop
