However, there is also the Publish Over SSH Plugin ( https://wiki.jenkins-ci.org/display/JENKINS/Publish+Over+SSH+Plugin ) which allows Jenkins to SSH into a remote host and run different commands, instead of starting a full Jenkins job, which requires the openjdk to be available. -- Craig ___ freebsd-virtualization@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"

Correct. > Does that mean that I need to configure my VM, so that it comes up with a > known IP, so that > it can be entered on this configuration page? Correct. Though, normally you don't need to perform any special configuration for the IP address as long as the networking configuration is correct. The VM just needs to be configured to obtain an IP address via DHCP. Later on it should be persistent in dnsmasq. An IP address could be obtained either from the dnsmasq leases file or from arp cache for example. > Also, the VM, that is spawned, it must have openjdk installed?

I think here the URI should be 'bhyve:///system'.
Or you could tweak libvirt.conf and assign the bhyve url value to the
'uri_default' parameter.

py-libvirt problems with bhyve
Hi,
I did the following:
(1) Set up libvirt, taking Roman's latest port, and configuring bhyve
support:
http://people.freebsd.org/~rodrigc/libvirt/libvirt-bhyve.html
(2) Installed the py-libvirt port.
I wrote this code:
import libvirt
import sys
conn = libvirt.openReadOnly(None)
if conn == None:
print 'Failed to open connection to the hypervisor'
sys.exit(1)
try:
print conn.listAllDomains()
#print dir(conn)
dom0 = conn.lookupByName("bhyve")
except:
print 'Failed to find the main domain'
sys.exit(1)
but when I ran the code, I got this error:
[]
libvirt: QEMU Driver error : Domain not found: no domain with matching name
'bhyve'
Failed to find the main domain
Can anyone tell me how to write a py-libvirt program to
start/stop a bhyve VM?
Thanks.
