Hi, I can configure a network port attached to a VM to be a VLAN trunk using the following commands (when using Open vSwitch): ovs-vsctl set port tap103i1 trunks=10,20,30 ovs-vsctl set port tap103i1 vlan_mode=trunk How can I do this on the webinterface? Cheers, Tobias

My IBM server is also not the newest model, it's 3 years old. The processor is a Intel Quad-Core Intel Xeon E5320 1.86 GHz (8MB L2 cache) and I have 2 250GB SATA Disks (Mirror). So perhaps I have to upgrade my hardware for more perfomance =(

sorry for the little information =( * server1 is a physical server * server2 is a kvm-vm running on an IBM x3400 Server (NOT server1!)

I'm only using Ubuntu Server 10.04.1!

How can I check that fairsched is really disabled?

I have exactly the same troubles. A VM with 2 vCPUs and virtio-net has an extremely bad network performance: root@server1:~# iperf -i 10 -m -t 120 -c server2.tobru.ch ------------------------------------------------------------ Client connecting to james.tobru.ch, TCP port 5001 TCP window size...

I don't see a reason to migrate PVE to Ubuntu. PVE is a server "tool" and Debian is the best distribution for server installations. The reason for my little experiment with Ubuntu was to have a nice and updatet desktop around the nice proxmox tools. But a server doesn't need a desktop, or at...

I agree with tom, I only did that for fun and don't run any production VMs on this host. There were a few issues with the package installation, but they could be resolved without troubles. And you have to manually create the bridge and the storage.

FYI: Open vSwitch has reached 1.0. So it would be a great addition to Proxmox. I will make a test installation and report my findings...

I did that and it works! Installed a Ubuntu Server 9.10 64 Bit Added the Proxmox Repos Installed the Proxmomx Kernel and Packages That's all.

One more information: "KVM on Host1" is Ubuntu Server 9.10, not Windows

Hi, Finally I added a DualPort Intel NIC to the AMD System. 03:00.0 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet Controller (rev 06) 03:00.1 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet Controller (rev 06) Here are the iperf results: KVM on Host1 ->...

Hi, I added the following card to my AMD system: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20) Here are some iperf tests KVM on Host1 -> Host1 [ 3] local 10.0.0.26 port 43720 connected with 10.0.0.10 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0...

Not really. I don't expect native network performance, around 10% less performance would be ok. I did some further test and startet some iperf tests on my two different hosts (see post above). This is what I get: virtio KVM on Host2 -> Host2 [ 3] local 10.0.0.26 port 56369 connected with...

Here are some hardware details host1:~# cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 107 model name : AMD Athlon(tm) 64 X2 Dual Core Processor 5000+ stepping : 2 cpu MHz : 2600.000 cache size : 512 KB...

Hi, The KVM Guests have poor network performance. I tried several things, like changing the adapter type... Here are some iperf tests: Host1 to Host2: 942Mbit/s Host1 to OpenVZ Guest on Host2: 941Mbit/s KVM Guest (virtio) on Host1 to Host2: 300 - 442Mbit/s KVM Guest (e1000) on Host1 to Host2...

I can't create any VM's on this node anymore. So I can't reproduce this error... But if I remember correct, I did the following steps: Created new VM (KVM): Disk Storage: LVM (local2) Disk Type: virtio Installed Ubuntu Server 9.10 inside this VM Added 2nd harddisk: Disk Storage: LVM (local2)...

Yes, that's right, I have a problem with the LVM =) The missing Volume Group "quimby" is on the 2nd drive of VM 21. And the 2nd drive of VM 21 is the Logical Volume /dev/local2/vm-121-disk-2 which is on the host of this VM. So I don't understand is why the host has a problem with this VG, which...

Hi, I created a LVM Volume in a KVM VM (don't ask me why!). Now I have some troubles with this vm, when I try to start it, the following messages tell me that it can't find the VG created in this VM (ID 121, name quimby: server:~# qm start 121 Couldn't find device with uuid...

Oh yes, sorry! I was confused because I only saw the size of the master volume. Would be great if this can be improved... Thanks! So finally I created a "fake" volume on the master server which has the same name as the volume group of the 2nd HD in the slave server. I added this storage as LVM...
