[Xen-users] Can't create guest using libvirt ( libvirtError: internal error: libxenlight failed to create new domain )

  • To: xen-users@xxxxxxxxxxxxx
  • From: Charles Gonçalves <charles.fg@xxxxxxxxx>
  • Date: Thu, 01 Dec 2016 11:43:26 +0000

  • List-id: Xen user discussion <xen-users.lists.xen.org>
Trying to create guest using the following command : 

sudo virt-install \
    --name testxn2 \
    --connect xen:/// \
    --memory 512 \
    --vcpus 1 \
    --disk /var/lib/libvirt/images/testxn2.img,size=6 \
    --location ubuntu-16.04.1-server-i386.iso \
    --graphics none \
    --extra-args 'console=ttyS0,115200n8 serial' \
    --network network=default \
    -d \
    -v

A dry run runs ok, but when running for real, got the following output:

Tryied to stop apparmor as suggested on similar issues appeared on a quick google search.  Also tryied to change virt-create parameters, but no effect!
Any Ideas what could be doing this problem?
