So the problem coud be due to the openvz patches ? As I am only running KVM, and there are regularly bugs due to openvz patches, I would prefer a stock 2.6.32 RHEL kernel, in a separate branch, as it was the case for 2.6.35... Alain

Hi, You are not at the latest version. For example, my kernel is 2.6.32-50, pve-firmware is 1.0-14, abd so on..., but it is not a big deal for this problem. Can you give more details on your hardware. What type of Raid controller do you use, how many disks in your raid 10, what kind of disks...

Yes, I don't understand that this line does not show up in the output. AFAIK, there is no option for this command, so it is strange... In my opinion, it would be displayed even if the result was very low... Here is a rather bad result for one of my test server with Proxmox 2.0 beta3, in Raid...

Hi, I don't see in pveperf output the Fsyncs/second line, and the time to resolve DNS seems to me very bad. The Fsyncs/second figures are the key parameter to have a good idea of IO performance, so it could be that they are indeed very bad... Alain

I just upgraded a server, and I can confirm. I have also an Aladin USB Dongle (for flexlm license manager), and it does not work anymore with 0.15-2. It was working before. I was also using kernel 2.6.35 (for KVM), and now I moved to the supported kernel 2.6.32-6. Message is : # qm start 118...

No, time was not correct on second node (more than an hour difference with first node). Indeed, I forgot to configure an NTP server on second node. After it was done, all is now OK, I can access both node without a login popup. Thanks for the hint ! Alain

Hi all, I did not see other people reporting this problem, but I think it is a bug at least on my installation. I setup a test cluster of two nodes with Proxmox 2.0. I log in one of the node, and both nodes are displayed correctly in the web interface, but I can only access the node where I log...

It will work with IDE, but performances (IO) will be much lower than virtio. You should try. Virtio is stable for Linux VMs. It is just a matter to remove the disk, then re-add it as virtio... Alain

Why not usung virtio disks with Linux machines ? It is my default choice for (KVM) linux VMs, and should show as good (or almost identical) performances as SCSI, as it is included in kernel. Alain

Hi Tom, My University (Paris VI), was using exclusively Cisco switchs, but they decided to go for Allied Telesis, AT8000GS/24 and 48 ports, POE or not, due to the cost. They are reliable switches, with a CLI as they should, and a good documentation. They divided by two the cost of the network...

Hi, As I have only one raid array (all in raid 10), and it is hardware raid, the answer is obviously yes. # pveperf /dev/md0 CPU BOGOMIPS: 36265.53 REGEX/SECOND: 811415 df: `/dev/md0': No such file or directory df: no file systems processed DNS EXT: 58.15 ms DNS INT...

I already saw the same behavior. I think the reason is that the backup is using the free PE of the volume group for the snapshot. When the snaphot is removed after the backup, you come back to 4 GB PE free. The message you oultined in red : [code) /dev/dm-2: read failed after 0 of 4096 at 0...

My main concern is not in fact the end of the official support. My servers are on rather safe network. Only some VMs are facing Internet, and they are all KVM, so rather isolated. But my big concern is the migration path. There are two huge changes : Proxmox-ve 2.0, a completly new API, new...

Hi Tom, Thanks for your answer. I see that indeed there are several options. In fact, the smallest raid volume I can build is 1 TB (the size of one HD). And yes, I could add afterwhile other raid volumes, format them as xfs or other filesystem, extend LVM volume group, or create LVM logical...

Hi all, I just installed Proxmox 2.0 beta 3 on a new Dell PE R510 server, with 12x 1 TB drives, a Perc H700 Controller (a rather good raid controller), configured in Raid 10. As I have a very big array (6 TB), I chose to format using ext4, typing at boot 'linux ext4' I have very low...

Thanks also for the information. It can be usefull too in my organization. Alain

Hi, I did not know remoteApp, but a little search on Internet shows it is seamingly a remote desktop management console for various applications, including HyperV. It can be installed for exemple under Windows 7 32 bits, where HyperV won't work. So, it is in my opinion no wonder if it is...

Latest kernels, 3.1 and above , seem to have nested kvm for Intel CPU too (not activated by default). See for example : http://www.mjmwired.net/kernel/Documentation/virtual/kvm/nested-vmx.txt Alain

Hi Jeremy, Make an iso from your DVD, copy the iso on your server, in /var/lib/vz/template/iso (if the iso is bigger than 2 Go, it won't work with the web GUI 'upload', use an scp client as filezilla for example), then configure your VM to boot on this iso. It is the way I always do it...

You should report to Hetzner the errors you see, and ask them how to fix it. They did an incorrect installation, regarding the standard of Proxmox-ve. They certainly did a custom install, perhaps trying to improve some aspects (?). But we don't know what they did exactly, so it will be hard to...
