Sorry about the extra parameters on the virt-install. The "Actual results" and "Expected Results" should have: "virt-install -l http://192.168.2.251/tftpboot/lab/tst031/f19-x86_64 --ram 1024 --disk /dev/vg_guests/guest2 --name F19-64"
Aha! <dariof> darnok: 'cause I think I've seen something like that, having to do with the fact that it by defaults look for 'xenbr0' <dariof> darnok: "it" being the libxl driver (or so I think) .. <darnok> dariof, Right on the money: rror: libxl_exec.c:118:libxl_report_child_exitstatus: /etc/xen/scripts/vif-bridge online [1326] exited with error status 1 <darnok> libxl: error: libxl_device.c:979:device_hotplug_child_death_cb: script: Could not find bridge device xenbr0 And sure enough, if I setup 'xenbr0' bridge (instead of 'switch') it magically works!

From tools/libxl/libxl.c libxl__device_nic_setdefault(): if (!nic->bridge) { nic->bridge = strdup("xenbr0"); if (!nic->bridge) return ERROR_NOMEM; }
Is there a default that libvirt uses? Meaning use the default one from libvirt instead of letting libxl set the default?
(In reply to Konrad Rzeszutek Wilk from comment #4) > Is there a default that libvirt uses? No. And in fact I'm confused about how lack of a bridge name made it past libvirt. E.g. if I try to create or define a domain with a bridge type interface that does not contain a bridge name (<source bridge='br0'/> subelement), I get the following error error: internal error No <source> 'bridge' attribute specified with <interface type='bridge'/> What is the libvirt domXML created for F19-64?
