Dear Daniel,
Thank you for the information. I think I should study more about libvirt's Node
Device functions.
Have a nice day.

Hi there!
Does anyone have a config file for libvirt-LXC, that makes it possible to:
1. Use all namespaces (user namespace in particular)
2. Run systemd inside a container.
Thanks!
Jan

Hi all,
I'm running a VM using libvirt+KVM and I have a disk performance issue.
The host is the following:
4 cores Intel Xeon 5140@2.33 GHz, 16 GB of RAM, SATA HDD, OS Debian Wheezy,
libvirt 0.9.12-11, QEMU-KVM 1.1.2+dfsg-2.
The guest:
1 CPU, 2 GB RAM running Debian 7.0, image in compressed qcow
Hey,
First of all, you don't need to set scheduler as deadline on VM. Just
disable it (elevator=none). The HV will handle it for the VM.
Furthermore, as generic performance optimization, I recommend you
disable swappiness on the HV, as well as zone reclaim.
I invite you to read this IBM paper:

Hi,
I am not using quemu, i am using XEN, is there any option to allow me to do
that?
In the libvirt documentation specify that those options are only available
on quemu.

For historical reasons the default is to leave the config file
present on the source machine. You can control this behaviour
though when triggering migration. There are an insane number
of possible scenarios...

Hi Daniel,
thank you very much for your explanation.
Now every fits into the picture. I run the tests you suggested and the numbers
make much more sense.
Thanks for stating the obvious but it was the first time I needed to compare
I/O.
Best regards,
Matteo

Dear member of libvirt team,
I hope the lxc could be dynamically reconfigured, such as the number of vcpu or
vcpu pinning.
According to http://libvirt.org/hvsupport.html , at present,
setvcpus(virDomainSetVcpus) and vcpupin (virDomainGetVcpuPinInfo) are not
supported by lxc driver.
I wonder if t
