Hi,
currently, I am planning to implement a command line based tool to query more
than one xends for their running domains at the same time.
Unfortunately, I cannot connect to any other xend as the local one. This is
what I was trying to do:
----------------------------------------------------------------------------------------------------
#!/usr/bin/env python
# -*- mode: python; -*-
import sys
import os
# add fallback path for non-native python path installs if needed
sys.path.append('/usr/lib/python')
sys.path.append('/usr/lib64/python')
from xen.xend.XendClient import server
from xen.xend import sxp
def parse_doms_info(info):
def get_info(n, t, d):
return t(sxp.child_value(info, n, d))
return {
'dom' : get_info('domid', int, -1),
'name' : get_info('name', str, '??'),
'mem' : get_info('memory', int, 0),
'vcpus' : get_info('online_vcpus', int, 0),
'state' : get_info('state', str, '??'),
'cpu_time' : get_info('cpu_time', float, 0),
'ssidref' : get_info('ssidref', int, 0),
}
def xm_brief_list(doms):
print 'Name ID Mem(MiB) VCPUs State Time(s)'
for dom in doms:
d = parse_doms_info(dom)
if (d['ssidref'] != 0):
d['ssidstr'] = (" s:%04x/p:%04x" %
((d['ssidref'] >> 16) & 0xffff,
d['ssidref'] & 0xffff))
else:
d['ssidstr'] = ""
print ("%(name)-32s %(dom)3d %(mem)8d %(vcpus)5d %(state)5s
%(cpu_time)7.1f%(ssidstr)s" % d)
server.bind('192.168.111.18:8000',)
xm_brief_list(server.xend_list_domains())
----------------------------------------------------------------------------------------------------
I am running this script form my xenhost1 (192.168.111.17) and want to query
xenhost2 (192.168.111.18). But I only get the local informations.
Even if I manually hack
class Xend:
"""Client interface to Xend.
"""
"""Default location of the xend server."""
SRV_DEFAULT = "192.168.111.18:8000"
into xen/xend/XendClient.py it's still the same.
telnetting to 192.168.111.18 to port 8000 and do a manual
GET /xend/domain/?detail=1
works nicely.
Maybe someone could give me a hint how to query a remote xen host with
XendClient.py?
Regards, Michael

from xen.xend.XendClient import getHttpServer
server = getHttpServer(...)
Of course, I'm not sure works all that well either.
I'd recommend using libvir (http://www.libvir.org). libvir speaks the
S-Expression/HTTP protocol pretty well. It also has python bindings.

Thank you, I'll give it a try and otherwise have a look at libvir. :)
