  3. Mount hosts directory to KVM

    Not having "bind type" mount points from hots to VM has always been one of our main pullbacks from using KVM more extensively. I am trying to avoid NFS, sftp or SAMBA as an option and have just been reading about VirtFS - 9p virtio drivers (http://www.linux-kvm.org/page/9p_virtio) I've found...

  5. Can only use ISO file that is physically available in storage folder "ISO Image"

    Hi, in my network there's a NFS providing ISOs to multiple OS distributions. Instead of copying all ISO files to the storage I would prefer to use a softlink. Therefore I have mounted the NFS to /mnt/nfs/<server> and created a softlink in <storage>/template/iso. The content of...
  6. [SOLVED] pfSense in a VM with HA

    I'm trying to figure out how I could install a pfSense VM and make it HA. I have a ceph cluster of 4 nodes (but there will be nodes added regularly), so I can give each node a public IP address on one of it's ethernet ports. Creating a bridge and adding that to the pfSense VM will give me a...
  7. Memory issues

    I have been trying to figure this one out by my self but I think I need some help with translation. One of nested Proxmox servers that has 4 LXC servers running (each using ~1G RAM) claims that it is using 14G out of 16G. What is the rest of the memory being used? root@vh0:~# cat /proc/meminfo...

  9. [SOLVED] PVE 6.0.x doesn't load kvm_amd (EYPC 7551)

    Please advise as I need to get production up and running again. Should I just revert back to the PVE 5.x version? Had to R&R due to no backups and a hardware failure. Upgraded/installed PVE6.0.1 on EYPC 7551 but it's not loading the virtualization module and manually doesn't seem to cut it...
  10. Shared ceph storage on a 5 node setup

    Hi everyone, Currently we are using SolusVM with 5 nodes each with: * 64GB of RAM * 4x 1TB SSD RAID-10 * 2x CPUs We're evaluating moving to Proxmox and use Ceph, as for the long-run it is future-proof, more scalable and easier to maintain than SolusVM. Also we're having problems with...
  11. Connect bluetooth speaker to Windows 7 KVM?

    Is there a way to connect my Cliptec bluetooth speaker to my Windows 7 32-bit KVM? I installed the Gigaware bluetooth drivers and it seems to have connected to it, however the speaker icon on the taskbar still shows red and that there are no audio devices available. I tried playing a youtube...

    Hi guys. My big is itching :) My big is a server with about 10 KVM clients that each host about 10 LXC containers (nested virtualization is the way to go these days.) Lately I have seen several "dev loop0" problems usually with I/O errors indicating a malfunctioning disk causing problems with...

  15. RAM consumption (Cannot allocate memory)

    Hi everyone, First of, I am well aware of the famous "Linux ate my RAM" page and I post here because my issue makes no sense. I am also aware of the usual RAM requirements of 1GB per TB or storage for ZFS, but again, seems a bit odd in my situation. I have 5 VMs on my server, of which only...

    I attempt to assign secondary IP address on a CentOS 7 KVM VM. My node is on OVH. I already added an IP (virtual mac etc) on the CentOS 7 VM and it's working fine.
