[libvirt-users] VM Performance using KVM Vs. VMware ESXi
Hi All
We are currently testing our product using KVM as the hypervisor. We are
not using KVM as a bare-metal hypervisor. We use it on top of a RHEL
installation. So basically RHEL acts as our host and using KVM we deploy
guests on this system.
We have all along tested and shipped our application image for VMware
ESXi installations , So this it the first time we are trying our
application image on a KVM hypervisor.
On this front i have done some tests to find out how our application's
response time is when deployed on KVM and then compare it with a VM
deployed on VMware ESXi. We have a benchmark test that basically loads
the application simulating a load of 100 parallel users logging into the
system and downloading reports. These tests basically use a HTTP GET
query to load the application VM. In addition to that i have taken care
to use the same hardware for both the tests , one with RHEL(Host)+KVM
and another with VMware ESXi. All the hardware specifications for both
the servers remain the same. The load test also remains the same for
testing with both the servers.
First observation is that the average response time on the VMware ESXi
is : 500 milli-seconds while the application's average response time
when deployed using RHEL(Host)+ KVM is : 1050 milli-seconds. The
response time of the application when deployed on KVM is twice as much
as when it is deployed using VMware ESXi.
I did few more tests to find which sub-system on these servers shows
varying metrics.
First i started with IOZone to find out if there is any mismatch in the
speed with which data is read / written to the local disk on the two VMs
and found that "Read" speed in the VM that was deployed using
RHEL(Host)+KVM was twice as slow as the VM which was deployed using
VMware ESXi.
For more on IoZone , Please refer : http://www.iozone.org/
more specifically the following IoZone metrics were twice as less when
compared to the server running with VMware ESXi:
Read
Re-read
Reverse-Read
Stride Read
Pread
Note: I had run the IoZone tests on the VMs on both the servers.
Second observation to be made was the output from the "top" command. I
could see that the VM deployed on RHEL(Host)+KVM was showing high
numbers for the following metrics when compared with the VM deployed on
VMware ESXi:
load averages
%sy for all the logical processors
%si for all the logical processors
i debugged further to find out which device is causing more interrupts
and found it to be "ide0" , See the output from the /proc/interrupts
file below:
The other interrupts apart from ide0 are pretty much similar to the VM
deployed using VMware ESXi.

Re: [libvirt-users] VM Performance using KVM Vs. VMware ESXi
Dear Jatin,
Maybe it’s a good idea first to implement Spice:
<video>
<model type='qxl' ram='65536'
vram='65536' heads='1'/>
<address type='pci'
domain='0x0000' bus='0x00' slot='0x02'
function='0x0'/>
</video>
<channel type='spicevmc'>
<target type='virtio'
name='com.redhat.spice.0'/>
<address type='virtio-serial'
controller='0' bus='0' port='1'/>
</channel>
Spice should be installed on the host.
Do you use virtio ?
Greetings,
Dominique.

Onderwerp: [libvirt-users] VM Performance using KVM Vs. VMware ESXi
Hi All
We are currently testing our product using KVM as the hypervisor. We are not
using KVM as a bare-metal hypervisor. We use it on top of a RHEL installation.
So basically RHEL acts as our host and using KVM we deploy guests on this
system.
We have all along tested and shipped our application image for VMware ESXi
installations , So this it the first time we are trying our application image on
a KVM hypervisor.
On this front i have done some tests to find out how our application's
response time is when deployed on KVM and then compare it with a VM deployed on
VMware ESXi. We have a benchmark test that basically loads the application
simulating a load of 100 parallel users logging into the system and downloading
reports. These tests basically use a HTTP GET query to load the application VM.
In addition to that i have taken care to use the same hardware for both the
tests , one with RHEL(Host)+KVM and another with VMware ESXi. All the hardware
specifications for both the servers remain the same. The load test also remains
the same for testing with both the servers.
First observation is that the average response time on the VMware ESXi is : 500
milli-seconds while the application's average response time when deployed
using RHEL(Host)+ KVM is : 1050 milli-seconds. The response time of the
application when deployed on KVM is twice as much as when it is deployed using
VMware ESXi.
I did few more tests to find which sub-system on these servers shows varying
metrics.
First i started with IOZone to find out if there is any mismatch in the speed
with which data is read / written to the local disk on the two VMs and found
that "Read" speed in the VM that was deployed using RHEL(Host)+KVM was
twice as slow as the VM which was deployed using VMware ESXi.
For more on IoZone , Please refer : http://www.iozone.org/
more specifically the following IoZone metrics were twice as less when compared
to the server running with VMware ESXi:
Read
Re-read
Reverse-Read
Stride Read
Pread
Note: I had run the IoZone tests on the VMs on both the servers.
Second observation to be made was the output from the "top" command. I
could see that the VM deployed on RHEL(Host)+KVM was showing high numbers for
the following metrics when compared with the VM deployed on VMware ESXi:
load averages
%sy for all the logical processors
%si for all the logical processors
i debugged further to find out which device is causing more interrupts and found
it to be "ide0" , See the output from the /proc/interrupts file below:
The other interrupts apart from ide0 are pretty much similar to the VM deployed
using VMware ESXi.
