macvtap direct and ip spoofing
Hi there. I have configured kvm domain (rhel6.4) with ethernet bridged over macvtap, and found no filtration applied except mac. 'virsh' just silently ignoring attributes 'filterref' and 'ip address' in different formats. No error on validate stage. Config examples: ... <interface type='direct'> <mac address='52:54:00:31:ae:1a'/>

Convincing libvirt to create a bridge device?
I was hoping that I could delegate creation of bridge devices to libvirt for address-less bridges, in order to not have to deal with the various ways distributions handle persistent network configuration, but while this creates a libvirt network... <network> <name>provision</name> <forward mode='bridge'/> <bridge name='brprov'/>

Making remote access to qemu://session easier?
This is frustrating: $ export LIBVIRT_DEFAULT_URI=qemu+ssh://remotehost/session $ virsh list error: failed to connect to the hypervisor error: no valid connection error: Operation not supported: Connecting to session instance without socket path is not supported by the ssh connection driver Has there been any thought given to making this easier?

Why are virsh vol-upload/vol-download so slow?
I was interested in using 'virsh vol-upload' and 'virsh vol-download', rather than mucking about directly with the filesystem. But while simply copying the image is relatively quick: # ls -l /var/lib/libvirt/images/centos-7-cloud.qcow2 -rw-r--r--. 1 qemu qemu 1004994560 Apr 15 2015 centos-7-cloud.qcow2 # time cp /var/lib/libvirt/images/centos-7-cloud.qcow2

Serial ports: vm vs bare metal
I'm running libvirt under Fedora 28. I would like to attach a USB device to a VM, but when I select "Redirect USB Device" from the "Virtual Machine" menu in virt-manager and then select the device, I get the error: USB redirection error spice-client-error-quark: Could not redirect [device name] at 1-11: Error setting USB device node ACL: 'Not authorized' (0)

libvirtd vs XDG_RUNTIME_DIR
I ran into an odd problem today. I wanted to share it here in the hopes of maybe saving someone else some lost time. When you run libvirtd as an unprivileged user (e.g., if you target qemu:///session from a non-root account), then libvirt will open a unix domain socket in one of two places: - If XDG_RUNTIME_DIR is defined, then inside $XDG_RUNTIME_DIR/libvirt/libvirt-sock - If

Hi, Are there some kind of UUIDs for Host and Guest ? If yes , how may I retrieve them programmatically ? My goal is to trace GUEST migrations. Thx for help. Regards, J.P.

Getting IP address of a lxc container via libvirt
Hello I wanted to understand if there is a way to get LXC container's ip address. - virDomainInterfaceAddresses API only works for qemu/kvm and not with the lxc driver. What other options do I have? Using enter-lxc-namespace is throwing this error: virsh -c lxc:/// lxc-enter-namespace <domain> --noseclabel /sbin/ifconfig libvirt: error : Expected at least one file descriptor

How do I close a console connection?

Subsequent calls to openConsole fail
