I have installed Proxmox inside of a virtual machine with a provider and want to create multiple small virtual machines out of it (nesting). I have come across issues trying to get the network working inside of these virtual machines. This is due to the provider using "MAC filtering" auto lo...

Nothing I can run?

Unfortunately this is a server I rent so getting them to remove each of the DIMMs test is not something I think can happen. Where/what what the error logs look like? and is there any alternative testing.

A few days ago I noticed that my server was getting drastically slower. Running memory benchmark tests show there is huge latency issues and speed issues. I have been running sudo memtester 51900 5 overnight now and it just finished 1/5. I did notice testing this with 1GB at first it took...

I have PBS backup job set to run daily but as you can see from the screenshot below I have way too many backups now I have the following settings inside the PBS but they seem to be getting ignored. What is the correct way to limit the amount of backups?

I have 6 disk in total and both /dev/sda and /dev/sdb are in RAID 1 whist the other 4 disks are part of a ZFS RAID 10. How would I go about removing the RAID 1 on /dev/sda and /dev/sdb to free up /dev/sdb - If possible without a reboot? cat /proc/mdstat Personalities : [raid1] [linear]...

I will give an example maybe I have it all wrong. Lets say I create 10 virtual machines and for a few brief moments use the full 24GB RAM using some sort of benchmark tool and it scored 15GB/s. Now if it used the full 24GB RAM usage the nodes total RAM usage would remain at 240/256GB until those...

As in if I was to run free -m inside the VM it would show 5GB usage 19GB free and 5/24GB on the Proxmox GUI graph. Would it not know that by Ballooning being enabled? The guide says "Memory ballooning (KVM only) allows you to have your guest dynamically change it’s memory usage by evicting...

From the tests I have ran I can see if I allocate a virtual machine 24GB min/max RAM once it uses the 24GB the total RSS memory will remain at 24GB until powered down. The only way around is when swap starts kicking in and it returns some unused RAM. Ballooning is enabled however setting the min...

I am looking to overcommit RAM by adding lots of swap to my node (2-3X the total amount of RAM) to swap out the reserved RAM that's not being used by the virtual machines. Is this a bad idea? If so why.

That would not cause the lockup issues?

No one? Can't find much on ZFS swap

How does this deadlock happen though? Does it only happen if swap uses too much of the ZFS ZVOL disk because I have lots free (currently using 1.5TB of 6TB)

Hello, I currently have 4 disks allocated to RAID 10 ZFS and require more swap space on my node and need to use some of that allocated ZFS disk. I have come across this https://askubuntu.com/questions/228149/zfs-partition-as-swap Which says all I need to do to add 10GB swap is run zfs create...

So I have noticed that when swap starts (currently set to swappiness 0) the swap that is taken actually reduces the current RSS memory a virtual machine has. For example if I allocated a virtual machine 10GB of RAM and it peaked at 10GB of RAM the reserved memory for that running machine would...

Not what I am asking :) Asking to see if there is a way to check if a virtual machine is running on top of Proxmox. qm would not be installed in a default cloud image.

I am curious is there any way to check if a virtual machine (KVM) is running on a Proxmox node? I have found multiple commands along the line of sudo lshw -class system & sudo dmesg | grep -i virtual but these just return a generic QEMU message. The only way I can think of is by running...

Could this also be what's causing the issue for me? https://www.mail-archive.com/pve-devel@lists.proxmox.com/msg02453.html other than this I can't find others having this same issue. I do have an arc limit though /etc/modprobe.d/zfs.conf #Max Ram Used by ZFS - 64GB options zfs...

Running echo 3 | sudo tee /proc/sys/vm/drop_caches has reduced the nodes memory from 70% to 55%. It is running ZFS (limited to 64GB) but that does not take account for that much of a drop based off arcstat size reduction. Is there any way to force the node to reduce the resident set size (RES)...

If I run htop -s PERCENT_MEM on the node I can see there are multiple virtual machines allocated RAM they are not using Example this VM id 159 is reserving 10.8GB of RAM However it's usage over the last hour shows as peaking at that almost an hour ago qm guest exec 159 -- free -m {...
