Hi, i tried to upgrade a cluster today but some hosts can't be added again to the new cluster. i upgraded all hosts from datacenter1 and the first node became the master of the new cluster. the first node of second datacenter could also be added to the cluster, but all other nodes failed...

hi, i have two minor suggestions for people that use custom rulesets. I can understand if you guys argue that you don't want to support customization of the ceph stack. 1. show mounted storage size based on "ceph df" rather than "rados df" this includes rule patterns like different root...

Hi, I was able to test a Storage Cluster backend for Proxmox yesterday. Since I only had to Server, which should run a replicated scenario and be able to add more servers I chose GlusterFS. The setup was really easy and I could add it using the PVE Gui and locally. I got 2 Server running a...

Hi, I have some issues backing up on a remote NFS share. Using compression (gzip/lzo) it take extremely long to backup all machines. During backup not all cores are used for compression. Is that an issue with vmtar? How can I convince vzdump to use all available cores? regards

Hi, i experienced a bug after the 2.0 upgrade. There were some issues that lvscan did execute properly, so I decided to reboot the machine. All vms could except one could be shutdowned using the web interface. The last kvm node can't be stopped, even with kill -9 <pid> I found some kernel...

Hi, i tried to migrate a 2.6.18 server to the 2.6.32 Kernel branch, but I have problems using a static arp table. There is one PHY adapter and two bridges not connected to the PHY interface. When I upgrade the kernel, only one subnet works. I set the arp entries with a script with "arp -Ds...

Hi, today I faced this problem during installation of a Ubuntu 10.04.3 KVM VM. I first thought that this was a BIOS or RAID Controller misconfiguration. I was using latest proxmox-ve-2.6.35 kernel, to have KSM support. When I changed to proxmox-ve-2.6.32, the problem disappeared. I found...

Kemari KVM Virtualization Synchronisation Hi, ii found a link on http://www.linux-kvm.org/page/KVM_Forum_2010#Presentations to http://kemari.sourceforge.net/ . The stats look quite good, but i do not see the real advantage compared to a DRDB setup right now.

Hi, i have a problem with the ext3 filesystem. First of all the backup is really slow, and the next day the proxmox VE has a huge Io wait of 30-70% I see kjournald processes and so on. When I reboot the machine with an fsck check, it recovers the journal and is performing quite well again. i...

Hi! I have Proxmox also running in a hosted environment where i only geht ftp backup space. So i added a curlftpfs mount on the local filesystem. There i can't backup a large VM because it eats up all my RAM. It would be nice to have an option, that does not tar the Archive, but simply rsync...

This morning, one KVM machine started to hang: # qm stop 102 trying to aquire lock...got timeout how can i force this? edit: i had to reset the whole server, because this was quite urgent!

Hi, since a couple of days i have issues with the hdd. proxmox shows IO delays and the external sata raid drive on which proxmox is installed. the kvm's with winxp are really slow, nearly unusable. how can i locate the responsible task that is causing the hdd load? the host only runs proxmox.

Hi, i recently ran into problems with serial devices and now i got an issue with a usb device. I normally do not use proxmox for hardware passthroughs, but i don't know how i can change the setup now easily. #lsusb Bus 003 Device 003: ID 03eb:2018 Atmel Corp. at90usbkey sample firmware (CDC...

hi, how do you guys solve the backup space at standard hosting provider sites? Well, there you just have a ftp share, where you can backup, but you do not have enough space to buffer the backups on the actual running host. I wanted to write the vzdump output directly onto the ftp share. my...

Hi! At one site i've got three Win2k3 Servers running on a proxmox VE environment. I have huge performance issues from the proxmox host to the KVM nodes. Here is some iperf output: [ 3] 225.0-226.0 sec 1744 KBytes 14287 Kbits/sec [ 3] 226.0-227.0 sec 5712 KBytes 46793 Kbits/sec [ 3]...

Hi, i would like to ask you about windows Licensing in KVM guests. Today i read an article in german about licensing of Windows Desktop OS' and Windows Server OS'. So here is my question: How many Windows XP's can i install per license (1 or 2?) How many Windows 2003 Server can i install (1...

hi, i usally use proxmox for virtualizing Linux Servers that actually do not need any GUI. Now i got an idea for another project to use proxmox, also. For this project several house automation services have to be run under a windows OS. My first thought was to run a Windows server and give...

Hi, atm I just oopy my NXServer Appliance but it would be nice to have something like a basis NXServer oder Linux Terminal Server. It would also be cool to use VNC inside it for Presentation. By now, I use a Gnome Desktop Environment and connect via NXClient, then I hand over the VNC Session...

Hi, i really love the OpenVZ templates, but i have several KVM instances running both with windows and linux. For linux i choose KVM when it comes to encrypted file systems or VPN. But my main Problem is a 1 GB OpenSUSE KVM installation (don't blame me, blame the client) that is really using 1...

Hi, it would be nice, to have a simple dns config on the proxmox host. for example add all hostnames configured in the webinterface in the /etc/hosts file and then use a service like dnsmasq. now it would be simple to use the proxmox server as a subdomain dns manager. for instance...
