Hello, At our latest backup jobs the backups of all OpenVZ-containers failed with massive output of I/O errors in the logfiles. After investigating this i traced it down to the snapshot-volume not growing but staying at 1G size. Available space on the VG is >1TB. # lvm dumpconfig | grep...

Hello, As i'm already struggling with systemd and/or its ugly siblings on 2 systems I was wondering if the proxmox team plans on implementing systemd with the upcoming release of debian jessie, which most likely will ship with systemd as standard. To prepare for the worst I just set up a...

I updated one of our nodes today (subscription repository). The node was running kernel version 2.6.32-23-pve before, update ended without any errors or warnings. At first reboot the system locked up after starting the first container. After disabling any Container or VM via single-user mode...

I just installed a new W2K8 R2 guest to one of our Proxmox hosts, installed virtio-drivers for disk, ballooning and network and just wanted to disable the windows write-cache, but i get an error about disabling the cache is not possible for that device. Another 2K8 R2 server is running with...

I had a little discussion with a friend about setting up a firewall/gateway with visualization (no dedicated hardware for firewall!) As I like it modular and variable, I'd set up a VM (KVM, no contianer) as firewall/gateway (shorewall), exclusively using the hardware interface connected to the...

I just ran into this problem on a server at our branch: http://forum.proxmox.com/threads/5565-quot-Missing-CD-DVD-driver-quot-when-installing-Windows-Server-2008-R2 Weird thing though: I'm using the same original DVD from which I installed another VM just a few months ago on the very same...

Due to disk performance problems on a new system with 3ware 9750-8i card I recognized proxmox is using the 3.26.00 version of this driver with no explicit support for the 9750. The debian 2.6.32 kernel already ships with the 3.26.02 version with support for this card. Would it be safe to use...

I want to add MSSQL-Backups from a Windows machine to our external backup routines. As planned Windows-tasks and automated tools proved to be utterly unreliable even for just simple copy-jobs to an network-drive, it should be managed completely from the debian-machine which is also rotating...

One of our Windows 2008 SP1 (64bit) servers is crashing occasionally under heavy Load. It just happened again while compressing an old database-backup (~5GB) on the guest. The (useless...) Windows-"Log" records 2 failures AFTER the Crash-Time logged by EventLog ("system has been rebooted at...

I need to seperate our surveillance cameras from the rest of our LAN, so i chose to do it by VLANs. The switch (cisco) supports VLANs; Camera ports are configured as tagged VLAN 2 ports, the LAG for the 4 Proxmox-Server NICs is untagged member of VLAN1 and VLAN2. What changes have to be made to...

We are using an HASP licence dongle within a Windows 2008 SP2 (not R2!) VM. The USB-Device is redirected to the VM at startup via "usb0: host=0529:0001" in /etc/pve/nodes/<node>/<VMID>.conf, which works (device is redirected to the VM), but Windows always needs an extra invitation by re-adding...

I just recognized our proxmox system isn't using the full ammount of RAM anymore... Unfortunately i can't tell since when this problem is persistent (how often do you check if you have "lost" RAM?...), i just recognized our Windows machine (MSSQL server) being utterly slow and having really poor...

I'm quite stuck on working out a solution for a network/server-setup i support since a few months... We have 3 branches connected via VPN (branch A DSL 6000, branch B&C DSL3000). The connection has quite long latencies, so i'd like to minimize traffic from client applications over this...

I have to migrate an open suse 10.3 machine i don't have root access to. It runs a small remote application used on 3 clients within our network. We've already discussed the virtualization with the company that set up the machine - from the licensing side there's no limitation whether it's...

Hello, I'm about to virtualize a Win2k8 (32bit) Standard server running on an ACER Altos G540 M2 (8 cores, 32G RAM). Don't ask about this configuration - it was not my fault ;) ANyhow - the database server (MSSQL) is painfully slow, especially because of the RAM limitation of the OS...
