Hi, I have two hosts installed with libvirt. We have just installed a latest version of libvirt on one of the hosts, version Compiled against library: libvirt 1.2.16 Using library: libvirt 1.2.16 Using API: QEMU 1.2.16 Running hypervisor: QEMU 2.3.0 The host hosting all our virtual machines runs an older version Compiled against library: libvirt 1.2.2 Using library: libvirt 1.2.2 Using API: QEMU 1.2.2 Running hypervisor: QEMU 2.0.0 I am now trying to manually migrate virtual machines to the host with the newest version of libvirt. I have copied the qcow2, img, and xml files of all the virtual machines to this host. The problem I am encounting is that the newer version uses "Host device eno1:macvtap" network source for its virtual interface, whisch is not the same as "Host device vnet18 (Bridge "br0")" in the older version. Not sure if this is something \i have to worry about. I have manuall copied all the files across, but when booting up the vm on the newset version ost it hangs up before booting (see screenshot attached). Please help me to fully boot up into this virtual machine. -- Regards, Sakhi Hadebe Engineer: South African National Research Network (SANReN)Competency Area, Meraka, CSIR Tel: +27 12 841 2308 <+27128414213> Fax: +27 12 841 4223 <+27128414223> Cell: +27 71 331 9622 <+27823034657> Email: sakhi(a)sanren.ac.za <shadebe(a)csir.co.za&gt;
