Hello, i read about virtualization! It's very interesting,so i decided to find out more about it! I made my first linux container but i need some help about the creation of a private network with double nat! Thank you!

Re: [libvirt-users] Error starting domain: internal error: missing IFLA_VF_INFO in netlink response

Hi Laine, Sorry to disturb you. It seemed this issue had been fixed in libvirt-1.2.2/libnl-3.2.22/linux-3.12. But we still got the error on PowerPC platform. I'll appreciate if you could give any suggestion. We are not sure if any netlink implementation in kernel space is missed. The scenario is a little complicated. We installed internal PF and VF kernel modules and want to use <interface type="hostdev" managed="yes"> syntax to start a guest domain with MAC address. # insmod fslinic.ko max_vfs=2 Freescale 10 Gigabit PCI Express Network Driver fslinic 0000:01:00.0: Multiqueue Enabled: Rx Queue count = 1, Tx Queue count = 1 fslinic 0000:01:00.0: Freescale (R) 10 Gigabit Network Connection fslinic 0000:01:00.1: Multiqueue Enabled: Rx Queue count = 1, Tx Queue count = 1 fslinic 0000:01:00.1: Freescale (R) 10 Gigabit Network Connection # insmod fslinicvf.ko Freescale 10 Gigabit PCI Express Network Driver # lspci -mk 00:00.0 "PCI bridge" "Freescale Semiconductor Inc" "Device 0440" -r20 "" "" 01:00.0 "Power PC" "Freescale Semiconductor Inc" "Device 0440" -r20 "" "" 01:00.1 "Power PC" "Freescale Semiconductor Inc" "Device 0440" -r20 "" "" 01:00.4 "Power PC" "Freescale Semiconductor Inc" "Device 0000" -r20 "" "" 01:00.5 "Power PC" "Freescale Semiconductor Inc" "Device 1957" -r20 "" "" 01:01.0 "Power PC" "Freescale Semiconductor Inc" "Device 0000" -r20 "" "" 01:01.1 "Power PC" "Freescale Semiconductor Inc" "Device 1957" -r20 "" "" 0001:00:00.0 "PCI bridge" "Freescale Semiconductor Inc" "Device 0440" -r20 "" "" 0002:00:00.0 "PCI bridge" "Freescale Semiconductor Inc" "Device 0440" -r20 "" "" # echo 1957 0000 > /sys/bus/pci/drivers/vfio-pci/new_id # echo 1957 1957 > /sys/bus/pci/drivers/vfio-pci/new_id # cat interface.xml <domain type='kvm'> <name>interface</name> <memory unit='KiB'>524288</memory> <currentMemory unit='KiB'>524288</currentMemory> <vcpu placement='static'>1</vcpu> <os> <type arch='ppc64' machine='ppce500'>hvm</type> <kernel>/dev/shm/uImage</kernel> <initrd>/dev/shm/ramdisk</initrd> <cmdline>root=/dev/ram rw console=ttyS0,115200</cmdline> </os> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/bin/qemu-system-ppc64</emulator> <controller type='usb' index='0'/> <controller type='pci' index='0' model='pci-root'/> <serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target type='serial' port='0'/> </console> <interface type="hostdev" managed="yes"> <mac address="00:e0:0c:00:20:01"/> <source> <address type="pci" domain="0x0000" bus="0x01" slot="0x00" function="0x04"/> </source> </interface> <memballoon model='virtio'/> </devices> </domain> root@t4240rdb:/var/volatile# virsh start interface error: Failed to start domain interface error: internal error: missing IFLA_VF_INFO in netlink response The debug message is as below: error : virNetClientProgramDispatchError:175 : internal error: missing IFLA_VF_INFO in netlink response Do you have any suggestion to investigate/debug this error?

[libvirt-users] Libvirt guest can't boot up when use ceph as storage backend with Selinux enabled
by Shanzhi Yu 08 Jan '15

08 Jan '15

Hi there, I met one problem that guest fail to boot up when Selinux is enabled with guest storage based on ceph. However, I can boot the guest with qemu directly. I also can boot it up with Selinux disabled. Not sure it is a libvirt bug or wrong use case. 1. Enable Selinux # getenforce && iptables -L Enforcing Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination 2.

[libvirt-users] trying to get "pages" output in virsh capabilities
by Chris Friesen 08 Jan '15

08 Jan '15

When running "virsh capabilities" one of my systems shows a couple entries for "pages" under host/cpu. (One for 4KB, one for 2MB.) On my other system I'm missing the "pages" entries. Is there something that I need to configure, or is this a libvirt version issue, or what? The system with the "pages" entries is running 1.2.9, while the system without them is running 1.2.2. Thanks, Chris

[libvirt-users] libvirt bridges rhel7
by Derek Yarnell 08 Jan '15

08 Jan '15

Hi, In RHEL5/6 we have been able to create bridges on our hyper-visor of a number of vlans (eg. em1 -> em1.483 -> br483) We would be able to see this br483 in the virt-manager drop down network choice at the end of creating a new host. On RHEL7 we are not using NetworkManager per the documentation[0] for bridges (and because it is not worth it). So a RHEL7 virt-manager (0.10.0) when connected to a libvirtd for RHEL6 (0.10.2) shows the bridge but when connected to a libvirtd for RHEL7 (1.1.1) it does not. So it isn't a virt-manager problem as it seems to be a difference in the backend libvirtd. You are able to manually specify the bridge device and it does work though. The `iface-dumpxml br483` command in virsh on RHEL6 and RHEL7 both are identical. I guess the question how does a libvirt client like virt-manager determine a iface is a usable bridge? [0] - https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/ht… Thanks, derek -- Derek T. Yarnell University of Maryland Institute for Advanced Computer Studies

[libvirt-users] use of qemu-kvm --chardev pipe, id=X, path=... argument ?
by Jason Vas Dias 06 Jan '15

06 Jan '15

Please can anyone enlighten me as to why linux qemu-kvm always creates the console on my terminal, when I am trying to direct all of its input and output to a pipe ? I have created : $ mkfifo /tmp/el6x32{.in,.out,.monitor} and use the command: $ /usr/libexec/qemu-kvm -M rhel6.4.0 -cpu n270 -smp 1 \ -hda /home/rpmbuild/OEL6/img/OEL6_32.img \ -kernel /home/rpmbuild/OEL6/boot/vmlinuz-2.6.39-400.215.14.el6uek.i686 \ -initrd /home/rpmbuild/OEL6/boot/initramfs 2.6.39-400.215.14.el6uek.i686.img \ -append 'root=/dev/sda rw selinux=0 enforcing=0 console=0' \ -m 2048 -k en-gb -nographic -vga none -vnc none -enable-kvm \ -chardev pipe,id=0,path=/tmp/el6x32 -monitor pipe:/tmp/el6x32.monitor But this ends up with the kernel's console on qemu-kvm's STDIO . I actually want the console to be redirected to take input from /tmp/el6x32.in and direct output to /tmp/el6x32.out - I thought that was what the above '-chardev pipe,id=0,path=/tmp/el6x32' should do if kernel boot params 'console=0' is also supplied ? Why isn't this happening for me ? Anyone got a guest to read console input from a pipe and direct console output to a pipe ? If so, how? Thanks in advance for any replies, Jason.

[libvirt-users] Console access for a user.
by Le Bris Gilles 03 Jan '15

03 Jan '15

Hi, I would like to allow a user (non-root) to access the console of his VM (he's got root access on it). Using sudo doesn't seem to work: /bin/virsh console vm error: failed to get domain 'vm' error: Domain not found: no domain with matching name 'vm' If I assign suid to virsh, I get: 'error: Failed to initialize libvirt' I don't see any information on Internet about this. What is the procedure to follow to get this result (QEMU conf, libvirt conf, etc)? Thank you in advance.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Good morning, I am not sure if this is a known issue or if I should raise as a bug. When using libvirt 1.2.11 on FreeBSD 10.1-RELEASE with bhyve, I have notice that a machine which defines: <interface type='bridge'> <mac address='52:54:00:88:44:08'/> <source bridge='bridge10'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </interface> <interface type='bridge'> <mac address='52:54:00:42:8f:c1'/> <source bridge='bridge11'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> Generates a bhyve command from domxml-to-native that contains the interfaces such that: - -s 2:0,virtio-net,tap0,mac=52:54:00:88:44:08 -s 3:0,virtio-net,tap0,mac=52:54:00:42:8f:c1 As a result, in this configuration, no network traffic works due to the duplication of the tap0 device in each command. When running two machines simultaneously, both are allocated to tap0, again causing issues. Is this a known issue?
