[libvirt-users] Destroy autostarted network on shutdown
by Jan Grashöfer 07 Dec '15

07 Dec '15

Hi all, I just ran into problem properly stopping a network. I have defined a network and network hook script to accomplish some preparations and cleanup. Testing my configuration (virsh net-start and virsh net-destroy) was successfully. Now I wanted to automate the lifecycle. Unfortunately I realized that an autostarted network has to be persistent and thus will not be destroyed (even if the host gets shutdown). As it won't be destroyed, my cleanup doesn't get executed and I run into trouble. What would be the preferred way to implement an autostarting and autostopping network? Thanks, Jan

[libvirt-users] virsh attach-device scripting ...
by Jean-Pierre Ribeauville 07 Dec '15

07 Dec '15

Hi, Did anybody ever try to script « virsh attach-device ...... < response.txt" in order to give virsh user and password needed when host is part of a ovirt cluster ? Cos , although I put in my response.txt two lines one for user the other for password , then it always asks question concerning password. ( username is correctly got from the .txt file.)

[libvirt-users] libvirt logging of virDomainAttachDeviceFlags()
by Jean-Pierre Ribeauville 07 Dec '15

07 Dec '15

Hi, When using « virsh attach-device ....." to add a channel device to a Guest , I see following entry in libvirt log : 2015-12-07 11:14:47.307+0000: 14551: debug : virDomainAttachDeviceFlags:10433 : dom=0x7f2a58252fc0, ........ Great !! But , when calling virDomainAttachDeviceFlags( ) from a C program , I got return code -1 but nothing appears related to virDomainAttachDeviceFlags( ) in the libvirt log file . Others libvirt calls of this C program are correctly logged . Did I misunderstand something ? To add traces I've added these lines within /etc/libvirt/libvirtd.conf log_level = 1 log_outputs="1:file:/var/log/libvirt/libvirtd.log" Thx for help. Regards, J.P.

[libvirt-users] virsh attach device equivalent in libvirt API
by Jean-Pierre Ribeauville 04 Dec '15

Hi, Is there an equivalent of "virsh attach-device -live -persistent " within libvirt API : virDomainAttachDevice() or virDomainAttachDeviceFlags() or ??? Thanks for help. Regards, J.P.

[libvirt-users] virsh athentification failure
by Jean-Pierre Ribeauville 04 Dec '15

04 Dec '15

Hi, I wrote a C program running in a KVM host. Part of it adds a Unix Channel device in all Guests in order to have a dialog from Host to Guest. As long as my host wasn't part of an Ovirt cluster , all was running fine. I added my host in a ovirt cluster , and then , when running the script creating the channel device ( by using "virsh attach-device --persistent -live ....." ) , I got following error : Please enter your authentication name: Please enter your password: error: failed to connect to the hypervisor error: no valid connection error: authentication failed: Failed to step SASL negotiation: -1 (SASL(-1): generic failure: All-whitespace username.) What's the user/password I've to use then ? BTW , I've seen that following channel device was added to the Guest at its creation : /var/lib/libvirt/qemu/channels/ad1a8b0e-f8b6-4038-be3d-275f38e66eb3.org.qemu.guest_agent.0 What's used for ? I presume I cannot use for my private purpose ? I sent this topic to ovirt and libvirt mailing lists , cos I don't know which forum is the right one for this kind of subject. Thanks for help.

[libvirt-users] FAIL: qemuxml2argvtest , FAIL: virsh-uriprecedence after make check

Hi there, I'm new to libvirt and I'm trying to install it on a Debian Jessie system. My goal is to create and use VMs from the command line. When I get to the $ make check (not as root) I am getting the message below. I am not sure if those "failed" messages should be corrected before starting to use libvirt, not sure how important they are. I will appreciate any hint or advise. Thanks. ========================================= libvirt 1.3.0: tests/test-suite.log ========================================= # TOTAL: 115 # PASS: 112 # SKIP: 1 # XFAIL: 0 # FAIL: 2 # XPASS: 0 # ERROR: 0 .. contents:: :depth: 2 FAIL: qemuxml2argvtest ====================== TEST: qemuxml2argvtest ........................................ 40 ........................................ 80 ........................................ 120 ...!.................................... 160 ........................................ 200 ........................................ 240 ........................................ 280 ........................................ 320 ........................................ 360 ........................................ 400 ........................................ 440 ........................................ 480 ........................................ 520 ............. 533 FAIL FAIL: virsh-uriprecedence ========================= TEST: virsh-uriprecedence !!!! 4 FAILED SKIP: virsh-all =============== ./virsh-all: skipping test: This test is very expensive, so it is disabled by default.

[libvirt-users] Error message doesn't make sense
by Tashi Lu 04 Dec '15

04 Dec '15

Hi everyone, I incidentally configured two IDE controller for my machine-1.2 VM(it might be virsh attach-disk to blame), and I got the error message "Only a single IDE controller is unsupported...". I can't understand this error message, I think it means I HAVE to configure two or more IDE controllers until I looked it up in the source. At libvirt-1.2.22/src/qemu/qemu_command.c: 4916 case VIR_DOMAIN_CONTROLLER_TYPE_IDE: 4917 /* Since we currently only support the integrated IDE controller 4918 * on 440fx, if we ever get to here, it's because some other 4919 * machinetype had an IDE controller specified, or a 440fx had 4920 * multiple ide controllers. 4921 */ 4922 if (qemuDomainMachineIsI440FX(domainDef)) 4923 virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", 4924 _("Only a single IDE controller is unsupported " 4925 "for this machine type")); I didn't dig VIR_DOMAIN_CONTROLLER_TYPE_IDE up, but reasoning from the comment, I think this error message should be something like "More than one IDE controllers is not supported for this machine type"
