  1. Which VM display settings for max video performance in VDI?

    Hi all, Running a small VDI environment with a selection of Windows 10 VM's. These are all accessed via MS RDP. They don't do anything particularly video intensive but since this is a for a remote teaching environment, a couple of the VM's do use classroom control software that monitors the...
  2. Proxmox 6.1 Apt-get Update fails DEFAULT INSTALL

    Hi all, this has been a problem that I have seen in the logs for various versions of proxmox. Task error apt-get update failed exit 100.... bla bla.... Its because I don't have a subscription for the enterprise repo. But this is a default install and I have not added the enterprise repo, only...
  3. Dell R920 VM Performance issues

    Hi all, Just spun up a couple of new Proxmox boxes, these are Dell R920's with 4 x Xeon E7 4880v2's 15 cores each, so 60 cores + hyperthreading. 512GB RAM in the boxes, local storage is a 22 disk RAID 10 of spinners. No SSD's yet, but still not slow. I have created 2 linux VM's and a windows...
  4. pveperf results opinion?

    Hi all, just curious as to my general performance on this new node. Without me telling you what the hardware is, how do these numbers look? And yes they have got spinning disks for the time being, not SSD's. But that will change. root@proxmox01:/mnt/convert# pveperf CPU BOGOMIPS: 598857.60...
  5. Migrating VM Disk from HyperV to Proxmox (qm importdisk) BOOT FAILED

    Hi all, I am trying to migrate a 1.4TB HyperV VHDX disk from a Gen2 machine to a new proxmox server. I exported the VM in HyperV and copied it overnight to the proxmox box via SFTP/SSH. I then made a new proxmox VM with no disk then ran qm importdisk 101 /blabla/disk2import.vhdx local-lvm. The...
  6. Differential Backups on PromoxVE - Replace VEEAM + HyperV?

    Howdy all, migrating another HyperV Cluster to Proxmox VE. I have been using Proxmox VE since 3.0 and love it. Have deployed single instances to 16 node clusters, including ceph, iscsi, you name it... In fact I have deployed Proxmox VE into some of the most prestigious organisations in the...
  7. Reducing backup storage requirements?

    Hi there, I am a fan of the out the box Proxmox backup solution. Its simple yet effective! However on larger clusters with many VM's, running daily full backups obviously means huge disk space requirements. I am a long time Proxmox user and have built several large clusters with it, but in...
  8. Found duplicate PV? Multiple block devices for same disk

    When I run vgdisplay I get the following messages: I have two iSCSI LUN's connected to this host, multipath-tools is NOT installed. When I run fdisk -l I see several /dev/sdX devices for the same LUN's as follows: What is going on here? I am having iSCSI problems and was wondering if this...
  9. Udev rule for changing 'max_sectors_kb' for all 'sd*' devices

    I am having a problem creating a udev rule that sets max_sectors_kb to 1024 for sd* (sda,sdb,sdc etc...) devices under /sys/block/. Specifically, a recent kernel change means the max IO is too large for my iSCSI SAN so I am trying to set it to 1024 on startup. I have tried the following from...
  10. Proxmox VE 4.2 MAJOR iSCSI bug?

    I have been spending the last 2 days trying to work out why I cannot restore or create any VM's onto my iSCSI backed LVM storage on a brand new 16 node Proxmox VE 4.2 cluster. The nodes are able to create logical volumes in the volume groups however when data starts writing, things grind to a...
  11. qmrestore extract tmp location?

    Hi guys, I am trying to restore a VM from a USB drive via the command line and have run into an issue. The restore fails with exit code 133 every time. My target storage is LVM backed with iSCSI, plenty of space. However, it appears that qmrestore tries to use /var/tmp as the location to...
  12. FEATURE REQUEST: iSCSI MPIO in GUI

    Hi guys, Just think having iSCSI MPIO configuration options in the GUI for cluster wide MPIO configuration would be a good idea. Saves having to create an MPIO configuration on every cluster node then present it for LVM in GUI. Tom
  13. 4.2 / New GUI timeframe?

    Hi there, I am about to carry out a major datacentre migration and during that time, an upgrade of our proxmox cluster. I have just seen that new packages have made their way into pvetest including 4.4 kernel and new GUI. Whats the timeframe for full release? Will it be out within the next...
  14. iSCSI any way to get Snapshots?

    Hi there, I am about to perform a restructure of our virtual environment and as such upgrade to 4.1. I currently present iSCSI to 16 servers, have a multipath device configured and LVM on top of that. Obviously I can't have snapshots on LVM since it required RAW VM disks. I just wondered if...
  15. iSCSI - Directory instead of LVM?

    This is just a quick one... I run a 16 node production proxmox cluster that in the immediate future will be taking down for an upgrade / rebuild to VE 4.x from 3.3. I am also going to be provisioning a lot more iSCSI storage on our 10Gbit SAN. Currently I present a couple of large LUNS to the...
  16. Backing up vm's with RAW disks, size?

    HI guys, I look after a 16 node VE 3.4 cluster who's primary storage is presented in the form of iSCSI backed LVM with MPIO devices configured. Obviously Proxmox only allows for RAW image format on this type of storage. So I have a VM that has a large disk, about 900GB, only 200 of which is...
  17. Specify port range in firewall GUI?

    Hi guys, Am I able to specify a destination port range when creating a rule on the firewall GUI? I only seem to be able to specify individual ports.
  18. IO Delay stats with iSCSI

    Hi guys, I operate a 16 node cluster with 10Gbit iSCSI through to a HP SAN as my VM storage. Performance seems excellent and I have MPIO configured on every host. However I noticed that the IO Delay stat on the host summary page moves between 0 and 3%. Mostly 0 but hovers around upto 3% every...
  19. 3.4 Memory Hotplug issue?

    Hi, when trying to enable memory hotplug on a VM (Windows Server 2012 R2 with VirtoIO drivers) I get the following error when trying to start the VM. The VM starts fine without memory hotplug. The VM has 8 cores (2 sockets x 4 cores) and 42GB of memory. kvm_alloc_slot: no free slot available...
  20. OpenvSwitch new OVSIntPort without reboot?

    Hi guys, I need to add a few new VLAN's to my infrastructure, one of which will be for backups that each of my 16 proxmox hosts will need to talk on. Therefore I need to add a new OVSIntPort to each host. I want to know if it is OK to make the new port in the GUI and then run the following...
