VNX latest features implemented
- 22/10/2016 - New attribute 'stp' added to <net> tags. Now VNX allows to individually control the activation of Spanning Tree (STP) protocol on virtual_bridge and openvswitch networks. For example:
<net name="Net1" mode="openvswitch" stp="on"/>
will activate STP on Open vSwitch suppproting net Net1.
Additionally, STP can be activated globally using the <netconfig> tag. For example:
... <vm_defaults/> <netconfig stp="off"/> ...
will activate STP in all virtual_bridge or openvswitch networks.
- Update VNX with vnx_update command
- Update the autoconfiguration daemon of your root filesystems with:
vnx --modify-rootfs your-rootfs.qcow2 --update-aced
[libvirt] ... virtio = yes
Note that in the case of FreeBSD images, you additionally need to edit the /etc/fstab to change the name of the devices /dev/ada0pX by /dev/vtbd0pX. For that reason, new rootfs images with a name extension "novirtio" have been added to be used with no virtio drivers.
vnx_download_rootfs -p lxc
vnx -f scenario.xml -x cmd1 -M vm1,vm2,host
will execute al, the <exec> tags defined in vm1, vm2 and the host.
<exec seq="createfiles" type="verbatim"> touch \ /tmp/file1 \ /tmp/file2 </exec>
