Re: [ovirt-users] Juniper vSRX Cluster on oVirt/RHEV

[FERNANDO FREDIANI]

Indeed, there is this problem wiht the virtio driver which creates this ,
sometimes huge bottleneck for machines tat do a fair amount of traffic.
Other than using DPDK OVS I would love to heard an alternative or a fix for
it. Currently being hit by this issue with no solution.

As you mention for a lab is fine but would be lovely to have a pretty
redundant scenario like this in production.

 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

Re: [ovirt-users] Juniper vSRX Cluster on oVirt/RHEV

[Charles Kozler]

Truth be told I dont really know. What I am going to be doing with it is
pretty much mostly some lab stuff and get working with VRF's a bit

There is a known limitation with virtio backend driver uses interrupt mode
to receive packets and vSRX uses DPDK -
https://dpdk.readthedocs.io/en/stable/nics/virtio.html which in turn
creates a bottleneck in to the guest VM. It is more ideal to use something
like SR-IOV instead and remove as many buffer layers as possible with PCI
passthrough

One easier way too is to use DPDK OVS. I know ovirt supports OVS in later
versions more natively so I just didnt go after it and I dont know if there
is any difference between just regular OVS and DPDK OVS. I dont have a huge
requirement of insane throughput, just need to get packets from amazon back
to my lab and support overlapping subnets

This exercise was somewhat of a POC for me to see if it can be done. A lot
of Junipers documentation does not take in to account such things as ovirt
or proxmox or any linux overlay to hypervisors like it does for vmware /
vcenter which is no fault of their own. They assume flat KVM host (or 2 if
clustered) whereas stuff like ovirt can introduce variables (eg: no MAC
spoofing)

Out of curiosity how much traffic can it handle running in these Virtual
Machines on the top of reasonable hardware ?

Re: [ovirt-users] Juniper vSRX Cluster on oVirt/RHEV

[Charles Kozler]

I hit a lot of errors when I tried to upload through the web UI. I tried
both remote URI and local file and both failed for me. I cant remember
exactly what they were but I recall its where I spent a lot of time
initially. I think it had something to do with the ovirt-imageio
function...something around that I couldnt get working right. Also, doing
the way I did it allowed me to quickly restart if I needed to by creating
an alias around dd command. I had to restart a bunch so it was useful. I
did this all on 4.0.1.1-1.el7.centos

@Work we're using Juniper too and oud of curiosity I downloaded the
qcow2 image and used the UI to upload it and add it to a VM. It just
works :-) oVirt++

Why didn't you just upload the qcow2 disk via the UI/API though?
There's quite a bit of manual work that I hope is not needed?
