[libvirt-users] [virtual interface] detach interface during boot succeed with no changes
by Yalan Zhang 08 Sep '22

08 Sep '22

Hi guys, when I detach an interface from vm during boot (vm boot not finished), it always fail. I'm not sure if there is an existing bug. I have confirmed with someone that for disk, there is similar behavior, if this is also acceptable? # virsh destroy rhel7.2; virsh start rhel7.2 ;sleep 2; virsh detach-interface rhel7.2 network 52:54:00:98:c4:a0; sleep 2; virsh dumpxml rhel7.2 |grep /interface -B9 Domain rhel7.2 destroyed Domain rhel7.2 started Interface detached successfully <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </controller> <interface type='network'> <mac address='52:54:00:98:c4:a0'/> <source network='default' bridge='virbr0'/> <target dev='vnet0'/> <model type='rtl8139'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> When I detach after the vm boot, expand the sleep time to 10, it will succeed. # virsh destroy rhel7.2; virsh start rhel7.2 ;sleep 10; virsh detach-interface rhel7.2 network 52:54:00:98:c4:a0; sleep 2; virsh dumpxml rhel7.2 |grep /interface -B9 Domain rhel7.2 destroyed Domain rhel7.2 started Interface detached successfully ------- Best Regards, Yalan Zhang IRC: yalzhang Internal phone: 8389413

[libvirt-users] Question about disabling UFO on guest
by Bao Nguyen 05 Aug '20

05 Aug '20

Hello everyone, I would like to ask a question regarding to disable UFO of virtio vNIC in my guest. I have read the document at https://libvirt.org/formatdomain.html *host* The csum, gso, tso4, tso6, ecn and ufo attributes with possible values on and off can be used to turn off host offloading options. By default, the supported offloads are enabled by QEMU. *Since 1.2.9 (QEMU only)* The mrg_rxbuf attribute can be used to control mergeable rx buffers on the host side. Possible values are on (default) and off. *Since 1.2.13 (QEMU only)* *guest* The csum, tso4, tso6, ecn and ufo attributes with possible values on and off can be used to turn off guest offloading options. By default, the supported offloads are enabl ed by QEMU. *Since 1.2.9 (QEMU only)* Then I disabled UFO on my vNIC on guest as the following configuration <devices> <interface type='network'> <source network='default'/> <target dev='vnet1'/> <model type='virtio'/> <driver name='vhost' txmode='iothread' ioeventfd='on' event_idx='off' queues='5' rx_queue_size='256' tx_queue_size='256'> *<host gso='off' ufo='off' />* *<guest ufo='off'/>* </driver> </interface> </devices> Then I reboot my node to get the change effect and it works. However, can I disable the UFO without touching the host OS? or it always has to disable on both host and guest like that? Thanks, Brs, Natsu

[libvirt-users] Clock skew on Win10
by Alex 03 Apr '19

03 Apr '19

Hi, I'm having a problem with significant clock skew on fedora29 with qemu-system-x86-3.0.0 and ibvirt-daemon-kvm-4.7.0. This is on my desktop and appears to happen between suspends of the host each night. It appears like the time just stops while the guest is suspended, of course, but then doesn't update once the guest is resumed. I'm pretty sure time is configured correctly on the Win10 guest. It's configured to be set according to Internet time and syncs with time.windows.com. How do I troubleshoot this further?

I am trying to connect a KVM-QEMU VM to OVS-DPDK vhostuser port. But, I am encountering a few errors. Since I am very new to libvrt and Linux I am not able to sort them out. Any guidance in this regard would be a great help.

[libvirt-users] Virt-Lightning: a cloud-like CLI for libvirt
by Gonéri Le Bouder 27 Mar '19

27 Mar '19

Hi all, Tl;dr: Virt-Lightning uses libvirt, cloud-init and libguestfs to allow anyone to quickly start new VM. Very much like a container CLI interface, but locally. -> https://github.com/virt-lightning/virt-lightning To validate my Ansible roles, I was looking for a way to quickly start and stop my test environments. I was looking for an experience similar to what we have with the containers. Virt-lightning takes a distribution name as main input. The output is the IP address of a freshly deployed VM on which I can run my tests. Virt-Lightning uses master QCOW2 images with backing file and avoid the use of DHCP, this to speedup up the first boot. The configuration is done by cloud-init. The whole deployment is rather fast. For instance, I can deploy 3 VM in 25s (Lenovo T580). cloud-init is used to create the user account, inject the SSH keys, prepare the network configuration and resize the file system. Regards, -- Gonéri Le Bouder

[libvirt-users] virsh snapshot-create-as: change umask on snapshots
by Mircea Husz 23 Mar '19

23 Mar '19

I scripted the creation of snapshots and it works fine. Now I'd like to run the script as non-root. virsh snapshot-create-as --domain hq-live-v01 \ --name snappy \ --diskspec vda,file=/var/lib/libvirt/images/hq-live-v01.snappy,snapshot=external \ --diskspec vdb,file=/var/lib/libvirt/images/hq-live-storage.snappy,snapshot=external \ --disk-only --quiesce --atomic This fragment creates the snapshots, but get created with mode 0600: -rw------- 1 qemu qemu 393216 Mar 19 17:08 hq-live-storage.snappy -rw------- 1 qemu qemu 1048576 Mar 19 17:08 hq-live-v01.snappy The user account is in the libvirt group and has permissions to do everything except delete the files created by the snapshot, all I need is to get the snapshots created with 0660 mode. This is on a Centos 7.6 installation. What knobs do I need to turn to control the umask? Thanks, -Mike

[libvirt-users] Error starting domain: internal error: Unable to add port vnet0 to OVS bridge br0
by Harsh Gondaliya 20 Mar '19

20 Mar '19

I have installed OVS from sources using the installation steps mentioned on this link: http://docs.openvswitch.org/en/latest/intro/install/general/ I had installed libvrt, KVM, QEMU and all the necessary packages using apt-get. My KVM-QEMU hypervisor has been running well. To add a VM with the port attached to OVS bridge I changed the XML domain file as per the instructions on this page: http://docs.openvswitch.org/en/latest/howto/libvirt/ But the when I start the VM using the Virtual Machine Manager I get the following error: *Error starting domain: internal error: Unable to add port vnet0 to OVS bridge br0* 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 1402, in startup self._backend.create() File "/usr/lib/python2.7/dist-packages/libvirt.py", line 1035, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: internal error: Unable to add port vnet0 to OVS bridge br0 My output for ovs-vsctl show: 3c28f516-dd5c-43cf-bea1-7c068668d1f6 Bridge "br0" Port "enp0s31f6" Interface "enp0s31f6" Port "br0" Interface "br0" type: internal ovs_version: "2.11.90" *However, when OVS is installed using apt-get rather than installing from source or tarball, all these steps work very well.* Please guide me why this error is occurring.

[libvirt-users] use dirty bitmap to backup raw images
by Zhan Adlun 19 Mar '19

19 Mar '19

Dear Sir, I use dirty bitmap to backup kvm raw images. I did not shutdown or suspend the vm when backup. I try to export backup as raw images or qcow2 images when doing full backups as the origin disk is in raw format, all backup jobs finish successfully. But only the raw images works, the guest os runs well. The qcow2 backup has data corruption and the guest os is in rescue mode.This happens all the time and no operation is done to the vm when doing backup. export as raw disk { "type": "drive-backup", "data": {"device": "drive-virtio-disk0", "target": "/datastore/centos.raw","sync":"full" ,"format": "raw"}} export as qcow2 disk { "type": "drive-backup", "data": {"device": "drive-virtio-disk0", "target": "/datastore/centos.raw","sync":"full" ,"format": "qcow2"}} After I suspend the vm, and export qcow2 disk, the disk works. Are there any limits when using bitmap to backup raw disks? For example , we should keep the backup disk in the same format as the origin when vm is running?

[libvirt-users] vlan tagging for openVSwitch
by lejeczek 15 Mar '19

15 Mar '19

hi everyone, I'm trying to get vlans tagged in libvirt as my switch's end (yes traffic will be leaving the host and into network switches) allows only tagged vlans. But with network as such: ... <portgroup name='vlan-55'> <vlan trunk='yes'> <tag id='55'/> </vlan> </portgroup> </network> and guest as: <interface type='network'> <mac address='52:54:00:15:00:26'/> <source network='ovsbr0' portgroup='vlan-55'/> <model type='virtio'/> </interface> When the guest is fully initialized vSwitch shows: ... _uuid : b3c130db-fa84-49f8-9cf5-824ec8cf3b81 bond_downdelay : 0 bond_fake_iface : false bond_mode : [] bond_updelay : 0 external_ids : {} fake_bridge : false interfaces : [35c0a914-a21a-43d7-9f63-adacffbb62bc] lacp : [] mac : [] name : "ovsbr0" other_config : {} qos : [] statistics : {} status : {} tag : [] trunks : [] vlan_mode : [] No tags, no trunks, no vlan mode??? Is there something I missed (in docs though I sroogled exensively) ? I also tried to add mode='trunk' into <tag id='55'/> and virsh does not complains but next time I edit the guest the mode bit is gone. My vSwitch's bridge has only one phys iface (into the net switch) and I tried setting that iface with tag/no tag, with vlan_mode/no vlan_mode but if guest is up with above libvirt's vSwitch initialization then guest cannot ping net switch no matter the setting for phys iface. I'm on Centos 7.6 with libvirt-4.5.0-10.el7_6.4.x86_64 & openvswitch-2.0.0-7.el7.x86_64. What can be the problem here? many thanks, L.

[libvirt-users] KVM-Docker-Networking using TAP and MACVLAN
by Lars Lindstrom 15 Mar '19

15 Mar '19

Hi everyone! I have the following requirement: I need to connect a set of Docker containers to a KVM. The containers shall be isolated in a way that they cannot communicate to each other without going through the KVM, which will act as router/firewall. For this, I thought about the following simple setup (as opposed to a more complex one involving a bridge with vlan_filtering and a seperate VLAN for each container): +------------------------------------------------------------------+ | Host | | +-------------+ +----------------------+---+ | | KVM | | Docker +-> | a | | | +----------+ +----------+ +--------------+ +---+ | | | NIC lan0 | <-> | DEV tap0 | <-> | NET macvlan0 | <-+-> | b | | | +----------+ +----------+ +--------------+ +---+ | | | | +-> | c | | +-------------+ +----------------------+---+ | | +------------------------------------------------------------------+ NIC lan0: <interface type='direct'> <source dev='tap0' mode='vepa'/> <model type='virtio'/> </interface> *** Welcome to pfSense 2.4.4-RELEASE-p1 (amd64) on pfSense *** LAN (lan) -> vtnet0 -> v4: 10.0.20.1/24 DEV tap0: [root@server ~]# ip tuntap add tap0 mode tap [root@server ~]# ip l set tap0 up [root@server ~]# ip l show tap0 49: tap0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN mode DEFAULT group default qlen 1000 link/ether ce:9e:95:89:33:5f brd ff:ff:ff:ff:ff:ff [root@server ~]# virsh start pfsense [root@server opt]# ip l show tap0 49: tap0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN mode DEFAULT group default qlen 1000 link/ether ce:9e:95:89:33:5f brd ff:ff:ff:ff:ff:ff NET macvlan0: [root@server ~]# docker network create --driver macvlan --subnet=10.0.20.0/24 --gateway=10.0.20.1 --opt parent=tap0 macvlan0 CNT a: [root@server ~]# docker run --network macvlan0 --ip=10.0.20.2 -it alpine /bin/sh / # ping -c 4 10.0.20.1 PING 10.0.20.1 (10.0.20.1): 56 data bytes --- 10.0.20.1 ping statistics --- 4 packets transmitted, 0 packets received, 100% packet loss / # ifconfig eth0 Link encap:Ethernet HWaddr 02:42:0A:00:14:02 inet addr:10.0.20.2 Bcast:10.0.20.255 Mask:255.255.255.0 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:4 errors:0 dropped:0 overruns:0 frame:0 TX packets:4 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:448 (448.0 B) TX bytes:448 (448.0 B) / # ip r default via 10.0.20.1 dev eth0 10.0.20.0/24 dev eth0 scope link src 10.0.20.2 CNT b: [root@server ~]# docker run --network macvlan0 --ip=10.0.20.2 -it alpine /bin/ping 10.0.20.1 PING 10.0.20.1 (10.0.20.1): 56 data bytes CNT c: [root@server ~]# docker run --network macvlan0 --ip=10.0.20.2 -it alpine /bin/ping 10.0.20.1 PING 10.0.20.1 (10.0.20.1): 56 data bytes The KVM is not reachable from within a Docker container (during the test firewalld was disabled) and vice versa. The first thing I noticed is that tap0 remains NO-CARRIER and DOWN, even though the KVM has been started. Shouldn't the link come up as soon as the KVM is started (and thus is connected to the tap0 device)? The next thing that looked strange to me - even though interface and routing configuration within the container seemingly looks OK, there are 0 packets TX/RX on eth0 after pinging the KVM (but 4 on lo instead). Any idea on how to proceed from here? Is this a valid setup and a valid libvirt configuration for that setup? Thanks and br, Lars

[libvirt-users] How to insert a dummy NIC
by wferi＠niif.hu 12 Mar '19

12 Mar '19

Hi, I have to host (with KVM) an appliance which does not use its second and third NIC. They have to be present in the guest, but they'd better stay totally disconnected from anything in the host. "Second" and "third" apparently means bus order. Let's consider virtio devices only. I think the best technical solution is adding -device virtio-net-pci,addr=0x3 and similar options to the KVM command line, without any corresponding -netdev options (better ideas welcome). QEMU emits "Warning: nic virtio-net-pci.2 has no peer" messages, but that's expected. I can even do this much using the <qemu:commandline> element, but libvirt assigns the 0x3 address to other virtio devices, leading to collision. Is there a way to "reserve" a bus address for such manually added devices without assigning explicit addresses to all other devices in the configuration? Things I also tried (and found inadequate): * Using "generic ethernet connection" for the dummy NICs. Close, but requires extra permissions for accessing /dev/net/tun, and technically feels a little inferior to using a peerless network device like above. * TCP tunnel server. Even more inferior, does not require extra permissions but leaves even looser ends (listening sockets). Also, the RelaxNG grammal does not let me specify a model for this interface type, so maintaining bus order with respect to the virtio interfaces is impossible. A grammar bug? * Using a dummy VLAN in the bridge. This is what I temporarily settled for, but this requires global agreement and still technically inferior, so I'd like to move away. * A <network> without forwarding. Still inferior, and also requires configuration sharing across the host cluster. -- Thanks, Feri

[libvirt-users] Obtaining the PID of a domain's QEMU process from C
by Shawn Anastasio 11 Mar '19

11 Mar '19

Hello all, I'm currently writing a C program that uses the libvirt API and I need a way to obtain the pid of a given domain's QEMU process. Specifically, I'm writing an ivshmem server that uses SO_PEERCRED to get the pid of clients that connect to it, and I would like to use that pid to look up the domain in libvirt to determine the proper domain ID to return to the client. As far as I can tell, libvirt doesn't expose this information in an easy to access manner. Of course it is possible to call `ps` and grep for the information I'm looking for, but I was hoping for a cleaner solution. If anybody knows how to do this, advice would be greatly appreciated. Thanks in advance, Shawn

[libvirt-users] why attach-disk can't be effective when the guest is booting
by Jianan Gao 07 Mar '19

07 Mar '19

Hi, When i use "virsh attach-device rhel disk.xml" when the guest is booting,then i can't find the disk in the guest after booting.But i can find it by "virsh domblklist rhel",and when i want to detach it from the guest and use "virsh detach-disk rhel vdb", i still can find the disk by "virsh domblklist rhel" The disk.xml is like: <disk type="file" device="disk"> <driver name='qemu' type='raw' cache='none'/> <source file="/var/lib/libvirt/images/foo.img"/> <target dev="vdb" bus="virtio"/> </disk> Libvirt-release is 5.0.0.4 and the qemu-kvm release is 3.1.0 So i want to know why it failed to attach-disk when booting,and why we design in this way.Maybe it's better to return failure if we can't use it like this.

[libvirt-users] virsh hangs when backup jobs run on the kvm host
by Zhan Adlun 07 Mar '19

07 Mar '19

Hi, Has anyone met the same problem that virsh hangs when there are some backup jobs running on the kvm host? I use dirty bitmap supported by qemu to do backups every 6 minitues. About a few hours later, I ran 'virsh list', It hung. Then I stopped the backup jobs ，nothing was getting better. I had checked the libvirt logs ，but found nothing useful . Maybe the high I/O caused the problem? or there are connection number limits when using virsh, because I use virsh to check the backup jobs are still running every 10 seconds? My os version is ' Ubuntu 12.04 LTS Release: 12.04 Codename: precise,Linux version 4.1.0-generic (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #1 SMP Wed Nov 9 02:04:23 CST 2016'. KVM version is 'QEMU emulator version 2.7.1(Debian 1:2.7+dfsg-3)'. Hoping for you reply. Thanks!

[libvirt-users] How do I close a console connection?
by Lars Kellogg-Stedman 05 Mar '19

05 Mar '19

I'm working on (re-) implementing serial console support in virtualbmc [1], and one of the issues I'm hitting right now is that after establishing a console connection via... self._stream = self._conn.newStream(libvirt.VIR_STREAM_NONBLOCK) self._domain.openConsole(None, self._stream, 0) ...I can't figure out how to close the console. Subsequent calls to openConsole fail because "a console connection is already open". I thought maybe I should close the stream, but that doesn't appear to be possible (there is a finish method, but it just tells me that "this function is not supported by the connection driver").
