[libvirt-users] Authenticating virsh with username and password
by Petr Kotas 26 Jun '17

26 Jun '17

Hi, I am new to libvirt and still learning, so thanks for any help. I am using libvirt configured with username and password. I need to utilize libvirt service "libvirt-guests.service" to shutdown all my VMs on system shutdown. Unfortunately it fails due to failed authentication. Jun 26 15:56:55 localhost virsh[13326]: All-whitespace username. Jun 26 15:56:55 localhost libvirt-guests.sh[13114]: Unable to connect to libvirt currently. Retrying .. 2Please enter your authenti Jun 26 15:56:55 localhost libvirtd[1155]: End of file while reading data: Input/output error Is it possible to specify user and password somehow? I cannot run kerberos or some other token based authentication. Thanks for any help. Kind regards, Petr Kotas

[libvirt-users] Configuring VMM for USB/Serial
by Brianna Moczynski 26 Jun '17

26 Jun '17

Hello, I keep receiving errors such as the following: Error rebooting domain: Timed out during operation: cannot acquire state change lock (held by qemuProcessReconnect) Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 90, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/asyncjob.py", line 126, in tmpcb callback(*args, **kwargs) File "/usr/share/virt-manager/virtManager/libvirtobject.py", line 83, in newfn ret = fn(self, *args, **kwargs) File "/usr/share/virt-manager/virtManager/domain.py", line 1378, in reboot self._backend.reboot(0) File "/usr/lib/python2.7/dist-packages/libvirt.py", line 2024, in reboot if ret == -1: raise libvirtError ('virDomainReboot() failed', dom=self) libvirtError: Timed out during operation: cannot acquire state change lock (held by qemuProcessReconnect) Whereby VMM loads, showing my VM in the "Paused" state and will not start, restart, shout down, etc. Restarting libvirt did not seem to have an effect on the issue. I ultimately solved it by removing and reinstalling the VM itself. Additionally, and I believe the issues may be somewhat related, I am having the following issues: libvirt not supporting forwarding ttys as usb serial devices (for pci serial cards (multiple serial ports)) virt-manager not supporting redirecting usb devices by vendor:device id I was wondering if you might have any suggestions on how to configure libvirt so that I do not have these issues. Thanks, BJM

[libvirt-users] About libvirt concurrency
by 马金舟 26 Jun '17

26 Jun '17

hi all: hello. I would like to ask a question about concurrency. Whether libvirt can achieve at the same time open 200 virtual machines. I try to open 200 virtual machines at the same time. oh on. when i am connected one of the virtual machines, i waited for a long time. I guess libvirt can't achieve concurrent operaction. I wish I could get a real result as soon as possible. thank you.

[libvirt-users] GPIO support in libvirt
by 陶缘 24 Jun '17

24 Jun '17

Hi, Dear libvirt experts: I am deploying a Virtual Machine to my hardware running linux. The thing is about the LED, the LED is controlled by GPIO operation. I do not know if my current qemu or libvirt can virtualize GPIO operation. And if yes, where can I find the options of qemu or libvirt(preferred) I am using qemu 2.4.0 and libvirt 1.3.2 Appreciate if hear from you Thanks eddy

[libvirt-users] guest A from virbr0 can talk to guest B in virbr1 but not vice versa
by Travis S. Johnson 21 Jun '17

21 Jun '17

Hello, I came across an interesting problem in my home lab a few weeks ago as I'm prepping for my RHCE exam using Michael Jang study guide. I've been at this for days now, and I still can't wrap my head around how two or more virtual networks in default NAT configuration are even allowed to communicate with each other despite what the libvirt documentation said. Here's the excerpt I'm referring to in the wiki link here: http://wiki.libvirt.org/page/Networking#Forwarding_Incoming_Connections: > By default, guests that are connected via a virtual network with <forward > mode='nat'/> can make any outgoing network connection they like. Incoming > connections are allowed from the host, and from other guests connected to > the same libvirt network, but all other incoming connections are blocked by > iptables rules. Also here's another assertion from 'The virtual network driver' section in http://libvirt.org/firewall.html: > type=nat > > Allow inbound related to an established connection. Allow outbound, but > only from our expected subnet. Allow traffic between guests. Deny all other > inbound. Deny all other outbound. I have three virtual networks with the following configs: ----------------------------------------------------------------------------- <network connections='1'> <name>default</name> <uuid>9c6796be-d54e-42bc-bcbe-2e4feee7154a</uuid> <forward mode='nat'> <nat> <port start='1024' end='65535'/> </nat> </forward> <bridge name='virbr0' stp='on' delay='0'/> <mac address='52:54:00:5a:5d:0e'/> <ip address='192.168.122.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.122.2' end='192.168.122.254'/> </dhcp> </ip> </network> <network connections='1'> <name>outsider</name> <uuid>247e380a-8795-466a-b94a-5be2d05267bb</uuid> <forward mode='nat'> <nat> <port start='1024' end='65535'/> </nat> </forward> <bridge name='virbr1' stp='on' delay='0'/> <mac address='52:54:00:7f:a1:fb'/> <domain name='outsider'/> <ip address='192.168.100.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.100.2' end='192.168.100.254'/> </dhcp> </ip> </network> <network connections='1'> <name>besider</name> <uuid>cc714cce-dbba-452d-b2bf-d36084dcb723</uuid> <forward mode='nat'> <nat> <port start='1024' end='65535'/> </nat> </forward> <bridge name='virbr2' stp='on' delay='0'/> <mac address='52:54:00:59:67:7f'/> <domain name='besider'/> <ip address='192.168.110.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.110.2' end='192.168.110.254'/> </dhcp> </ip> </network> ---------------------------------------------------------------------------- Here is the output of the 'FORWARD' iptables chain rules on my host (still using firewall-cmd): ------------------------------------------------------------------------ Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 8967 14M ACCEPT all -- * virbr2 0.0.0.0/0 192.168.110.0/24 ctstate RELATED,ESTABLISHED 5262 279K ACCEPT all -- virbr2 * 192.168.110.0/24 0.0.0.0/0 0 0 ACCEPT all -- virbr2 virbr2 0.0.0.0/0 0.0.0.0/0 70 5832 REJECT all -- * virbr2 0.0.0.0/0 0.0.0.0/0 reject-with icmp-port-unreachable 0 0 REJECT all -- virbr2 * 0.0.0.0/0 0.0.0.0/0 reject-with icmp-port-unreachable 8510 13M ACCEPT all -- * virbr0 0.0.0.0/0 192.168.122.0/24 ctstate RELATED,ESTABLISHED 5177 275K ACCEPT all -- virbr0 * 192.168.122.0/24 0.0.0.0/0 0 0 ACCEPT all -- virbr0 virbr0 0.0.0.0/0 0.0.0.0/0 61 5100 REJECT all -- * virbr0 0.0.0.0/0 0.0.0.0/0 reject-with icmp-port-unreachable 0 0 REJECT all -- virbr0 * 0.0.0.0/0 0.0.0.0/0 reject-with icmp-port-unreachable 8612 13M ACCEPT all -- * virbr1 0.0.0.0/0 192.168.100.0/24 ctstate RELATED,ESTABLISHED 5172 273K ACCEPT all -- virbr1 * 192.168.100.0/24 0.0.0.0/0 0 0 ACCEPT all -- virbr1 virbr1 0.0.0.0/0 0.0.0.0/0 0 0 REJECT all -- * virbr1 0.0.0.0/0 0.0.0.0/0 reject-with icmp-port-unreachable 0 0 REJECT all -- virbr1 * 0.0.0.0/0 0.0.0.0/0 reject-with icmp-port-unreachable 0 0 ACCEPT all -- * * 0.0.0.0/0 0.0.0.0/0 ctstate RELATED,ESTABLISHED 0 0 ACCEPT all -- lo * 0.0.0.0/0 0.0.0.0/0 0 0 FORWARD_direct all -- * * 0.0.0.0/0 0.0.0.0/0 0 0 FORWARD_IN_ZONES_SOURCE all -- * * 0.0.0.0/0 0.0.0.0/0 0 0 FORWARD_IN_ZONES all -- * * 0.0.0.0/0 0.0.0.0/0 0 0 FORWARD_OUT_ZONES_SOURCE all -- * * 0.0.0.0/0 0.0.0.0/0 0 0 FORWARD_OUT_ZONES all -- * * 0.0.0.0/0 0.0.0.0/0 0 0 DROP all -- * * 0.0.0.0/0 0.0.0.0/0 ctstate INVALID 0 0 REJECT all -- * * 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited -------------------------------------------------------------------------- I have a VM in each network: nest1.example.com (virbr0) - 192.168.122.50 nest2.example.org (virbr1) - 192.168.100.100 nest3.example.net (virbr2) - 192.168.110.25 I'm quite aware the above iptables rules were added by libvirt, but I'm still managing the firewall primarily through the *firewall-cmd* command. >From what I gathered... ---------------------------------------------------------- nest3 can ping nest1 and nest2.

Each chunk associated with the virtual network in the chain, consisting of five lines, is exactly as described in the aforementioned link (http://libvirt.org/firewall.html) The virtual network in the top chunk of the chain can communicate with virtually all networks as opposed to the network in the last chunk that is consistent with the intention of the original design. I'm using CentOS 7.3 with libvirt 2.0. I even tried reproducing this with CentOS 6.9 as I thought it was possible the firewalld may have influenced the change, but I was still getting similar result. Right now, I'm not certain if this is already a reported known bug, but I'm highly convinced this configuration is unofficially unsupported for quite a while. Can someone confirm this? This is my very first mailing list submission ever, and I apologize in advance if I couldn't figure out how to conveniently search up a similar discussion as this one in the archive. If this is in fact near impossible to implement in accordance to the intended design, then I'd like to have this confirmation publicly included in the docs. Thanks, Travis Johnson

However, I am getting this error in the log file when it attempts to start it on boot up: 2017-06-19 07:15:18.491+0000: starting up libvirt version: 2.0.0, package: 10.el7_3.9 (CentOS BuildSystem <http://bugs.centos.org>, 2017-05-25-20:52:28, c1bm.rdu2.centos.org) qemu version: 2.6.0 (qemu-kvm-ev-2.6.0-28.el7_3.9.1), hostname: server.mydomain.lan LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin QEMU_AUDIO_DRV=spice /usr/libexec/qemu-kvm -name guest=MyVM,debug-threads=on -S -object secret,id=masterKey0,format=raw,file=/var/lib/libvirt/qemu/domain-1-MyVM/master-key.aes -machine pc-i440fx-rhel7.3.0,accel=kvm,usb=off,vmport=off -cpu Broadwell,+rtm,+hle -m 8192 -realtime mlock=off -smp 4,sockets=4,cores=1,threads=1 -uuid cb6f4d45-091d-47f8-931a-8daf6b0cf2b8 -no-user-config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/domain-1-MyVM/monitor.sock,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc,driftfix=slew -global kvm-pit.lost_tick_policy=discard -no-hpet -no-shutdown -global PIIX4_PM.disable_s3=1 -global PIIX4_PM.disable_s4=1 -boot menu=off,strict=on -device ich9-usb-ehci1,id=usb,bus=pci.0,addr=0x6.0x7 -device ich9-usb-uhci1,masterbus=usb.0,firstport=0,bus=pci.0,multifunction=on,addr=0x6 -device ich9-usb-uhci2,masterbus=usb.0,firstport=2,bus=pci.0,addr=0x6.0x1 -device ich9-usb-uhci3,masterbus=usb.0,firstport=4,bus=pci.0,addr=0x6.0x2 -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x5 -drive file=/var/lib/libvirt/images/MyVM.qcow2,format=qcow2,if=none,id=drive-virtio-disk0 -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x7,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -netdev tap,fd=28,id=hostnet0,vhost=on,vhostfd=30 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:0e:2e:75,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -chardev socket,id=charchannel0,path=/var/lib/libvirt/qemu/channel/target/domain-1-MyVM/org.qemu.guest_agent.0,server,nowait -device virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=org.qemu.guest_agent.0 -chardev spicevmc,id=charchannel1,name=vdagent -device virtserialport,bus=virtio-serial0.0,nr=2,chardev=charchannel1,id=channel1,name=com.redhat.spice.0 -device usb-tablet,id=input0,bus=usb.0,port=1 -spice port=5900,tls-port=5901,addr=127.0.0.1,disable-ticketing,x509-dir=/etc/pki/vdsm/libvirt-spice,seamless-migration=on -device qxl-vga,id=video0,ram_size=67108864,vram_size=67108864,vram64_size_mb=0,vgamem_mb=16,bus=pci.0,addr=0x2 -device intel-hda,id=sound0,bus=pci.0,addr=0x4 -device hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0 -chardev spicevmc,id=charredir0,name=usbredir -device usb-redir,chardev=charredir0,id=redir0,bus=usb.0,port=2 -chardev spicevmc,id=charredir1,name=usbredir -device usb-redir,chardev=charredir1,id=redir1,bus=usb.0,port=3 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x8 -msg timestamp=on char device redirected to /dev/pts/0 (label charserial0) ((null):3344): Spice-ERROR **: reds.c:4043:do_spice_init: statistics shm_open failed, Permission denied 2017-06-19 07:15:18.824+0000: shutting down However, when I start the VM manually through virt-manager, it starts up fine.

[libvirt-users] vendor_id state='off' not working as expected
by Sean Whalen 19 Jun '17

19 Jun '17

Hi All, I'm trying to counter VM detection methods for a malware sandbox, using Pafish as a benchmark tool. https://github.com/a0rtega/pafish I have <hyperv><vendor_id state='off'/></hyperv> defined in a Windows 7 domain on Ubuntu 17.10, but for some reason this just changes the hypervisor vendor to "Microsoft Hv" instead of the default "KVMKVMKVM" vendor. How can I remove the hypervisor vendor completely?

[libvirt-users] [qemu-kvm] Network bandwidth limits via libvirt
by 卓浩凡 16 Jun '17

16 Jun '17

Hi all, I try to understand why the network bandwidth limits are not applied to my ubuntu 16.04.2 VM (qemu-kvm driver) and I would need some insights. I create my VM network with virsh and when I issue a dumpxml on my network, I can see that bandwidth limits are set: virsh # net-dumpxml nat_limit <network> <name>nat_limit</name> <uuid>4b5e128d-9ad0-4ccc-9424-dee60b71861a</uuid> <forward mode='nat'> <nat> <port start='1024' end='65535'/> </nat> </forward> <bridge name='virbr1' stp='on' delay='0'/> <mac address='52:54:00:af:99:73'/> <bandwidth> <inbound average='10' peak='50' burst='10'/> <outbound average='128' peak='256' burst='256'/> </bandwidth> <ip address='192.168.123.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.123.2' end='192.168.123.254'/> </dhcp> </ip> </network> And the net info is: virsh # net-info nat_limit Name: nat_limit UUID: 4b5e128d-9ad0-4ccc-9424-dee60b71861a Active: yes Persistent: yes Autostart: yes Bridge: virbr1 Then, I create my VM, and the source of interface is the network, like this: virsh # dumpxml virt20 ... <interface type='network'> <mac address='52:54:00:a2:5b:10'/> <source network='nat_limit' bridge='virbr1'/> <target dev='vnet2'/> <model type='rtl8139'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> ... However when I send a big file with netper I don't see any limits applied to the transfer rate. I've checked the domain log and I didn't see any qemu command line argument related to bandwidth limits. Could you tell me why the network bandwidth limits can not work? Do network limits are managed in another way? Thanks. Below some information about my hypervisor: root@ubuntu-04:~# virsh -V Virsh command line tool of libvirt 1.3.1 See web site at http://libvirt.org/ Compiled with support for: Hypervisors: QEMU/KVM LXC UML Xen LibXL OpenVZ VMWare VirtualBox ESX Test Networking: Remote Network Bridging Interface netcf Nwfilter VirtualPort Storage: Dir Disk Filesystem SCSI Multipath iSCSI LVM RBD Sheepdog ZFS Miscellaneous: Daemon Nodedev AppArmor Secrets Debug Readline Modular qemu version: 2.5.0 Thanks, Netsurfed

[libvirt-users] Isolate VMs' network
by Chris 07 Jun '17

07 Jun '17

All, I'm trying to setup a network with some virtual machines, that can connect to each other and to the internet, but neither to the host nor to other VMs. Is there any preconfigured network filter or best-practice for this setup? Of course, I could setup iptables rules on the host, but I'd prefer libvirt to handle them. - Chris

These processes are expected to go away after they reply with all libvirt asks them for. However, it seems like the initialization cannot be completed precisely due to the fact that these processes don't communicate. There might be some details about qemu-system-alpha that are different when compared to, e.g. qemu-system-x86 and libvirt is not (yet) adapted to them, but I installed that emulator and libvirt daemon runs as usual. It looks like a problem in QEMU. Could you, as a workaround, try uninstalling that qemu binary from your system and restarting the service? Also, what versions of libvirt and qemu do you have installed? >Here is gdb output: > >$ sudo gdb -batch -p $(pidof libvirtd) -ex "t a a bt full" > batch.out >[mcc@eastie-fid4-com triage]$ cat
