Hi. I am running virtualbox 4.3 on Mac OS X 10.11.12 and libvirtd 1.3.1 (installed with brew). I want to control the virtual machines via virsh. On libvirtd, I enabled tcp mode, removed all the authentication etc.. It's a development environment, so no worries here. It allows me to make a call such as: virsh –c vbox+tcp://172.30.5.51/session list —all 172.30.5.51 being my Mac IP address. Virsh connects successfully to libvirtd (I see my request in the log) but the "list —all" returns an error. virsh -c vbox+tcp://172.30.5.51/session list --all error: Failed to list domains error: invalid connection pointer in virGetDomain Based on the debug logs, it appears the vbox driver is properly used 2016-03-03 22:27:44.415+0000: 18446744073709551615: debug : do_open:1003 : name "vbox:///session" to URI components: scheme vbox server <null> user <null> port -1 path /session (…) 2016-03-03 22:27:44.416+0000: 18446744073709551615: debug : do_open:1050 : trying driver 4 (VBOX) ... 2016-03-03 22:27:44.416+0000: 18446744073709551615: debug : virArchFromHost:181 : Mapped x86_64 to 32 (x86_64) 2016-03-03 22:27:44.416+0000: 18446744073709551615: info : virObjectNew:202 : OBJECT_NEW: obj=0x7fa41950b2c0 classname=virCaps 2016-03-03 22:27:44.416+0000: 18446744073709551615: debug : virArchFromHost:181 : Mapped x86_64 to 32 (x86_64) 2016-03-03 22:27:44.416+0000: 18446744073709551615: info : virObjectNew:202 : OBJECT_NEW: obj=0x7fa41a208da0 classname=virDomainXMLOption 2016-03-03 22:27:44.416+0000: 18446744073709551615: debug : vboxConnectOpen:460 : in vboxOpen 2016-03-03 22:27:44.416+0000: 18446744073709551615: debug : do_open:1065 : driver 4 VBOX returned SUCCESS But later there is this error: 2016-03-03 22:27:44.420+0000: 18446744073709551615: debug : virThreadJobSet:96 : Thread 18446744073709551615 (virNetServerHandleJob) is now running job remoteDispatchConnectListAllDomains 2016-03-03 22:27:44.420+0000: 18446744073709551615: debug : virEventPollCleanupTimeouts:526 : Cleanup 2 2016-03-03 22:27:44.420+0000: 18446744073709551615: debug : remoteDispatchConnectListAllDomainsHelper:1219 : server=0x7fa419700040 client=0x7fa4196037c0 msg=0x7fa41a201280 rerr=0x700000415d40 args=0x7fa419602c90 ret=0x7fa419600ad0 2016-03-03 22:27:44.420+0000: 18446744073709551615: debug : virEventPollCleanupHandles:575 : Cleanup 5 2016-03-03 22:27:44.420+0000: 18446744073709551615: debug : virConnectListAllDomains:6701 : conn=0x7fa41950afe0, domains=0x700000415c40, flags=3 2016-03-03 22:27:44.420+0000: 18446744073709551615: debug : virEventPollMakePollFDs:401 : Prepare n=0 w=1, f=5 e=1 d=0 2016-03-03 22:27:44.420+0000: 18446744073709551615: debug : virEventPollMakePollFDs:401 : Prepare n=1 w=2, f=7 e=1 d=0 2016-03-03 22:27:44.420+0000: 18446744073709551615: debug : virEventPollMakePollFDs:401 : Prepare n=2 w=3, f=9 e=1 d=0 2016-03-03 22:27:44.420+0000: 18446744073709551615: debug : virEventPollMakePollFDs:401 : Prepare n=3 w=4, f=11 e=1 d=0 2016-03-03 22:27:44.420+0000: 18446744073709551615: debug : virEventPollMakePollFDs:401 : Prepare n=4 w=8, f=12 e=1 d=0 2016-03-03 22:27:44.420+0000: 18446744073709551615: debug : virEventPollCalculateTimeout:338 : Calculate expiry of 2 timers 2016-03-03 22:27:44.420+0000: 18446744073709551615: debug : virEventPollCalculateTimeout:346 : Got a timeout scheduled for 1457044069419 2016-03-03 22:27:44.420+0000: 18446744073709551615: debug : virEventPollCalculateTimeout:359 : Schedule timeout then=1457044069419 now=1457044064420 2016-03-03 22:27:44.420+0000: 18446744073709551615: debug : virEventPollCalculateTimeout:369 : Timeout at 1457044069419 due in 4999 ms 2016-03-03 22:27:44.420+0000: 18446744073709551615: info : virEventPollRunOnce:641 : EVENT_POLL_RUN: nhandles=5 timeout=4999 2016-03-03 22:27:44.421+0000: 18446744073709551615: error : virGetDomain:203 : invalid connection pointer in virGetDomain 2016-03-03 22:27:44.422+0000: 18446744073709551615: debug : virThreadJobClear:121 : Thread 18446744073709551615 (virNetServerHandleJob) finished job remoteDispatchConnectListAllDomains with ret=-1 The full log is here http://pastebin.com/raw/83Fgs5MZ I've been digging around but can't find anything I should change in my configuration or in virtualbox. I poked in the libvirt code, but I am not a C developer, so can't really figure it out. Any chance somebody sees a solution to this? There must be something obvious that I don't see… Thanks! _________________________________________________________________________________________________________________________ Ce message et ses pieces jointes peuvent contenir des informations confidentielles ou privilegiees et ne doivent donc pas etre diffuses, exploites ou copies sans autorisation.
