openSUSE KVM getting started notes

Some sparse notes on installing KVM on openSUSE locally

Configure libvirtd

Firstly, lets not have to be root every time I want to use virt-manager and without using policy kit.  In /etc/libvirt/libvirtd.conf uncomment and set

unix_sock_group = "libvirt"
unix_sock_ro_perms = "0770"
unix_sock_rw_perms = "0770"
auth_unix_ro = "none"
auth_unix_rw = "none"

(https://doc.opensuse.org/documentation/htmlsingle/openSUSE_122/opensuse-kvm.html#sec.libvirt.connect.auth.libvirt.traditional)

Set default url

I'm just using kvm locally and I don't want to have to type virsh -c qemu:///system every-time to admin on the command-line so I create

~/.config/libvirt/libvirt.conf

and add

uri_default = "qemu:///system"

Now I can just type

virsh list --all

(http://libvirt.org/uri.html)

virsh command hosts

virsh nodeinfo dump CPU and RAM info for the hypervisor 

virsh commands domain management

virsh list --all list info on all vm (domains)

virsh (start|shutdown|reboot|reset) domain

virsh (suspend|resume) domain

virt-viewer domain - open the graphical console for the domain

virsh commands domain info gathering

virsh dominfo domain - show overview of domain (name, cpu, state etc)

virsh domstate domain - show the state of the domain (shut off, running etc)

virsh dumpxml domain - dump the xml configuation for the domain to stdout

virsh edit domain - open the xml configuration for the domain in $EDITOR

virsh define (file) - import a domain from an xml config
