In my attempts to write a shell script to create VMs quickly I've got oneliners working fine i.e.
# qm create 9999 --name vmtest --bios ovmf --efidisk0 data:0,efitype=4m,pre-enrolled-keys=1 --boot "order=net0;scsi0" --cores 1 --sockets 1 --cpu host --memory 2048 --net0 model=virtio,bridge=vmbr0...
Hi everyone,
I have a server with 2 x 1TB storage - raid 1, 64GB of ram, AMD 5600G CPU. I created 1 VM where i use cPanel with 16 GB ram, and i can see that the PVE host jumped up to 80% (almost 50GB) RAM usage. What can cause this? I went through the forum posts and i see this can be just...
I've had an unexpected shut down on a VM that hosts a web server 2 times. Both at 6am, so obviously the first thing I need to do is find whats running at 6am on those days. The shut down appears to be more of a Kill than a shut down. From syslog it appear to be saying it's out of memory and...
I've read the NUMA wiki here: https://pve.proxmox.com/wiki/NUMA and the admin guide regarding NUMA here: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#qm_virtual_machines_settings however I still have some questions.
* Is NUMA only useful if your PVE *host* has more than 1 physical...
How much in theory PVE 8 requires RAM for its own usage? It runs on 1 TB SSD with ZFS. If I remember it correctly, the rule of thumb says: 1TB of storage equals to 1GB of RAM usage for ZFS based system...
I have on server with 32 GB of RAM and mentioned above drive installed Proxmox 8 with 3x...
Hi guys,
In the company where I'm working, we have a Cluster composed of 8 nodes that are connected through a 1Gb ethernet network directly to a Switch.
On the nodes we mostly run Kubernetes, DNS Servers and some other services. The problem is that on each node, the process corosync is using...
Hi all, one of the problems I am trying to get to the bottom to is, Proxmox thinks my OPNsense VM is using 6 gigs of RAM when it's only using 400mb or something? I first simply assumed this would be something to do with ballooning feature, and working as intended if that were desired - but it's...
Hello!
Is there any way to make memory bars colored by type of data that's stored in it? I mean, currently it shows you almost 100% of RAM if you use half of RAM by VM's and other half is ZFS cache.
My point is to separate bar into multiple colors to make it clear what is cached and what's not...
Hi all,
Have the backup server working, but one thing which seems odd, the amount of memory it's using while there is no running tasks.
the server has 32gb in total and it's using 16.82gb. It seems high to me with no jobs running. Rebooted and memory was around 1-2Gb (would need to reboot...
Hi All,
Coming from 20 years as a professional in Windows (2 years of hands-on Linux) I'm having issues with fully grasping cgroups. I recently upgraded my server cluster and am I encountering OOM kills regularly (a few times per day). I have a single cgroup (just out-of-the-box config). My...
Hi,
We had recently a node that restarted suddenly without any warnings.
The machine was running pretty capped RAM wise.
I downloaded the logs from the node in question but i don't see any trace in them.
all i see is the start phase, nothing interesting before
Can you lead me to a log file...
Hi,
I have some Ubuntu 22.04 VMs with qemu-guest agent installed and I've notice that the memory usage shown in the GUI is completely different from memory stats within the Ubuntu guest OS. Is it a problem of the guest agent? Does it computes memory usage as (used+buff/cache)/total instead of...
Hello everyone,
I'm not used to the forum and it's rules so very sorry if make a mistake or if my thread is not at it's right place...
So I have an issue with a little pve host that is actually a sort of mini network oriented computer with 4NICs and the following CPU :
4 x Intel(R) Celeron(R)...
Saw a mini PC with a Ryzen 7 3700U. I know that this processor is outdated, may this device consider small power consumption but big processing power?
My main purpose is to install OpenWRT on the Proxmox as a Internet router. May simply learn docker, container and linux, use the virtual machine...
On PVE 7.2-3, I created VM (linux Debian) with 4 GB of memory for example (or more), but inside the VM, this is only 915 MB.
debian@test:~$ free -mh
total used free shared buff/cache available
Mem: 915Mi 113Mi 759Mi 0.0Ki...
Hello,
server with 32GB of memory and made 16GB available for the VM. But in the web interface it shows the graph with memory above 80%. Can someone explain to me why this is happening?
Hi,
We are experiencing an issue that one of the VM (windows server) in our Proxmox cluster keeps stopping at regular intervals. We have checked the Syslog for OOM messages 'cat /var/log/syslog | grep OOM'. But does not get any output. On checking the summary in the Proxmox interface, we could...
Ich betreibe 2 mal eine OPNSense als KVM auf unterschiedlichen Servern
Bei beiden habe ich das Problem das innerhalb der Opensense lediglich 1 GB Memory verfügbar ist obwohl mehr zugeordnet ist.
Dies egal ob mit oder ohne balooning
hat jemand vielleicht einen tip?
Hi
I imagine some VPS hosting companies have ways to sell more memory than their servers actually have. How do they do this? Any advice for making the most of your server memory?
A few ideas so far:
* Use containers rather than VMs - pretty obvious
* Make sure KSM (Kernel Samepage Merging) is...
Hi, I have deployed a Win10 Vm on a 64 GB Ram node and have allocated it 32 gb. After installing the Balloon Drivers the VM shows correct memory usage but the node summary still shows the incorrect usage , no zfs used and cache/buffer is at 3700k only. I have tried old virtio drivers too . How...
