Re: [ovirt-users] [Ovirt 4.0.6] Suggestion required for Network Throughput options

2017-07-04 Thread TranceWorldLogic . 
Hi All,

I tried using hwrng as source for VM I got below error.

qemu/backends/rng-random.c:44:entropy_available: assertion failed: (len != -1)

Please help to understand it more.

Thanks,

Hi Yaniv,

I tried looking into rng direction and I found below stats.
I am not familiar with rng device but it look to me /dev/urandom giving me
better option.
But I am unaware how can I use urandom device in ovirt.

 Hi,

 To increase network throughput

Re: [ovirt-users] [Ovirt 4.0.6] Suggestion required for Network Throughput options

2017-06-30 Thread TranceWorldLogic . 
Your understanding is correct issue only due to encryption/decryption
process but not got idea why not word.
I found that in centos 7 we not have install rng-tools.

Do it required to install for random generator ?

I have changes nothing I just increase number of queues in vnet. It
diffenetly increase throughput and create multiple softIRQs in VM.
But for normal traffic this all things are not required it gives 10G
throughput.

Thanks,

Interesting - I had assumed the bottleneck would be the
encryption/decryption process, not the network. What do you set exactly?
Does it matter in non-encrypted traffic as well? Are the packets (and the
whole communication) large or small (i.e, would jumbo frames help) ?

But still not see any improvement in throughput.

Would please check do I missing some virtio module ?

One more finding, if I set queue property in vnic profile then I got good

 Interesting, as I've read the default (1000) should be good enough for
 10g, for example.

 Are you actually seeing errors on the interface (overruns) and such?

Hi,

I am using host as Centos 7.3 and guest also centos 7.3
it have 3.10 kernel version.

But I not see virtio-rng in guest VM. Is this module come with kernel or
separately I have to install ?

Thanks,
~Rohit

Interesting, as I've read the default (1000) should be good enough for 10g,
for example.

Are you actually seeing errors on the interface (overruns) and such?

Perhaps use ifup-local script to set it when the interface goes up?

For ipsec, probably best to ensure virtio-rng is enabled.

[ovirt-users] [Ovirt 4.0.6] Suggestion required for Network Throughput options

2017-06-29 Thread TranceWorldLogic . 
Hi,

To increase network throughput we have changed txqueuelen of network device
and bridge manually. And observed  improved throughput.

But in ovirt I not see any option to increase txqueuelen.
Can someone suggest me what will be the right way to increase throughput ?

Note: I am trying to increase throughput for  ipsec packets.

Thanks,
~Rohit
