Network interface persistence
by Sverker Abrahamsson 26 Mar '18

26 Mar '18

I have a number of vm's running under Ovirt 4.2, most are CentOS 7 and one Debian. Issue is that when multiple network interfaces are assigned they don't persist but it variates at boot which interface will be which. I've tried various methods, setting UUID and HWADDRESS in the ifcfg file and a file /etc/udev/rules.d/70-persistent-net.rules file like the below: SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1a:4a:16:01:63", KERNEL=="eth*", NAME="eth0" SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1a:4a:16:01:6d", KERNEL=="eth*", NAME="eth1" I've also tried in the gui to change the network profile each virtual card is attached, but even then the interfaces in vm will be oposide of what I had intended. How to accomplish with Ovirt to get network interface persistence? The Debian vm is an appliance so I can't log in to it to change network interfaces. /Sverker

Juniper vSRX Cluster on oVirt/RHEV

Hi All - Recently did this and thought it would be worth documenting. I couldnt find any solid information on vsrx with kvm outside of flat KVM. This outlines some of the things I hit along the way and how to fix. This is my one small way of giving back to such an incredible open source tool https://ckozler.net/vsrx-cluster-on-ovirtrhev/

Re: [ovirt-users] Problem to upgrade level cluster to 4.1

Two of these VMs are configured with the custom-property 'macspoof'. That property is not supposed to be used since 4.0 (IIRC). Nevertheless, defining this property for version 4.1 should solve this problem, see [1]. The third VM is in a weird state - it cannot be updated because the host it runs on doesn't support the number of CPUs defined for this VM. You can either shut this VM down during the cluster upgrade or try to migrate it to another host with more CPUs available. Unfortunately, I can't correlate those issues with the VMs you mentioned, but if you'll start with with the first issue you'll find which one of them is that 'third VM'.

Passing VLAN trunk to VM
by Simon Vincent 26 Mar '18

26 Mar '18

Is it possible to pass multiple VLANs to a VM (pfSense) using a single virtual NIC? All my existing oVirt networks are setup as a single tagged VLAN. I know this didn't used to be supported but wondered if this has changed. My other option is to pass each VLAN as a separate NIC to the VM however if I needed to add a new VLAN I would have to add a new interface and reboot the VM as hot-add of NICs is not supported by pfSense.
