Hi, I've noticed huge write amplification problem with thinly provisioned logical volumes and I wondered if anyone can explain why it happens and if and how can be fixed. The behavior is the same on Centos 6.8 and Centos 7.2. I have a NVME card (Intel DC P3600 -2 TB) on which I create a thinly provisioned logical volume: pvcreate /dev/nvme0n1 vgcreate vgg /dev/nvme0n1 lvcreate

Hi there was a mail a while back on this list about using the LD_PRELOAD feature on Solaris in order to override the location of nsswitch.conf for smbd so only it would use winbindd. I did some digging and came up with the code at the bottom of this mail ( I've overridden every file open call I could find, but I think it's only the _open() call which is actually necessary ). Initial

Hi All, First time mailing here. I have installed on a CentOS 7.0 KVM (with DPDK and OVS) one Deep Packet Inspection VM. I have one channel and some virtual traffic generator. The traffic is lost between dpdk vhostuser and the DPI VM. The setup is attached. Any suggestions or ideas? Regarding the OVS+DPDK configuration, the following configuration is already made: - SELINUX is disabled - QEMU

I'm running libvirt 0.10.2 and qemu-kvm-1.2.0, both compiled from source, on CentOS 6. I've got a working blkio cgroup hierarchy which I'm attaching guests to using the following XML guest configs: VM1 (foreground): <cputune> <shares>2048</shares> </cputune> <blkiotune> <weight>1000</weight> </blkiotune>

Thanks for answers,but as I see libvirt call ovs-vsctl that tries to connect to ovs-vswitchd socket,that have rw to root.how can I specify socket permissions in vswitchd?

I added libvirt-users@redhat.com back to the Cc for this response. Please don't remove the list address when responding to postings on a mailing list. A message to the list is *much* more likely to reach someone who knows the answer than is a private message to a single person.

The error that you're showing doesn't appear to be related to permissions; the "ovs-vsctl del-port" command requires that you specify the port that you want to delete. --Justin On Mar 6, 2014, at 2:05 AM, Vasiliy Tolstov <v.tolstov@selfip.ru> wrote: > Hello!

A huge thank you to mario from the ''openvswitch on Xen 4.1'' post. I was having some trouble with using openvswitch with Xen 4.1 (I''m currently migrating from 4.0.1) until I saw his post and noticed that the xl.conf needed the full path to the networking script. Made this change and all is good now. Thank you. I would like to contribute what I have for using

Hi a small update on this. I just migrated the vm from the site to my laptop and fired it up. The exact same xml configuration (except file paths and such) starts up and bursts with 50Mb/s to 115Mb/s in the guest. This allows only one reasonable answer: the cpu on my laptop is somehow better suited to emulate IO than the CPU built into the host on site. The host there is a HP proliant microserver

For the benefit of those running OEL (Oracle Enterprise Linux) or OVS, be aware that under 2.6.0rc4 facter doesn''t properly recognize OEL in /usr/lib/ruby/site_ruby/1.8/facter/operatingsystemrelease.rb. A diff for a fix is below; probably not the best fix but if you need it work now, this''ll do it for you. I''ve already filed a bug:

Hello, I have defined an ovs network with libvirt (virsh net-define ovs.xml) and created a vm that will connect to that network with virt-install. Although the vm port appears normally if i do an ovs-vsctl show, when i try to set this port as a mirror port for all the traffic in the bridge, the command is executed normaly, but then i cannot see any traffic on the interface. Could you give me

I am running NOX controller with a python script that prints out the destination mac and the source mac for each packet arriving at the now controller and then floods it out. So here's what happening: With em1 connected, all the packets that arrive at em1 are coming to the controller and printing out the details. However, without em1 connected to the OVS, when I have the following setup:
