J65nko · #2 **(View Single Post)** 3rd December 2014

The remainder of the Makefile:

Code:

lsimg   :      
        ls -ltr ${IMAGEDIR}

list    :
        virsh list --all

start   :
        virsh start ${DOMAIN} 

shutdown:
        virsh shutdown ${DOMAIN}

undefine:
        virsh undefine ${DOMAIN} 
        rm -rf ${IMAGEFILE} 

info:
        virsh dominfo ${DOMAIN}

dumpxml:
        virsh dumpxml ${DOMAIN}

sysinfo:
        virsh sysinfo

version:
        libvirtd --version
        virsh --version
        virt-install --version
        virt-xml-validate --version
        virt-clone --version
        virt-manager --version
        #virt-top --version
        #virt-df --version

Some examples of using it:

Code:

# make
virt-install \
        --prompt \
        --connect=qemu:///system \
        --name="OBSD-x3" \
        --ram=2048 \
        --vcpus=2 \
        --description 'OpenBSD virt-install with serial' \
        --os-type=unix \
        --os-variant=openbsd4 \
        --cdrom=http://hercules.utp.xnet/snapshots/amd64 \
        --disk path=/var/lib/libvirt/images/OBSD-x3.img,size=8 \
        --disk path=/var/lib/libvirt/images/OBSD-x3_ports,size=8 \
        --network bridge=br0,model=virtio \
        --graphics vnc \
        --serial dev,path=/dev/ttyS0 \

You also can edit this XML definition and use it to create a new guest, as explained in virsh(1):

Code:

  virsh dumpxml <domain> > domain.xml
  vi domain.xml 
  virsh create domain.xml
