Hi, Running the backups is causing hosts across the cluster to lose data, presumably because the backups are heavy, causing latency. Other than trying to stagger the backups, are there any other tricks someone could share?

I changed the IP of a host and rebooted it but it still shows the old IP in the console, https://192.168.19.242:8006. The IP was changed to .240 so why is it still showing the old one? UPDATE: I was able to get this working so this question can be closed.

I've been using pass-through USB for some time now and started wondering if I could expand that to using keyboard, mouse and video to real hardware. For example, being able to use a physical keyboard, mouse and video monitor with one of the VMs on the host.

I'm trying to get a physical display on one of the VMs for development work. It would be easier to have a physical machine so I'm trying this first. In fact, better would be if I could get full KVM control of a vm but I've not found any info on if that's possible or not. I've connected a usb to...

I've read snippets here and there that there is a way to install the Ubuntu ARM version on a Proxmox host running Intel Xeon chips. E5-2690 to be exact. I cannot find anything that confirms this or shares what virtual CPU I should be using when trying to install such an OS. Can anyone share...

I set up a temp cluster so I could migrate vms from the old host to the new host. When done, I wanted to remove the node (called p) from the cluster but I get this. # pvecm delnode p Killing node 1 unable to open file '/etc/pve/corosync.conf.new.tmp.78679' - Permission denied # pvecm status...

I'm able to ssh between hosts but using the cluster, I cannot move vms around without getting key related errors. I've run this set of commands on first one host then all of them and no change. pvecm updatecert -f systemctl stop pve-cluster systemctl start pve-cluster I have read everything I...

I know, it's an old question and I've read many many posts but nothing seems to solve the problem. I'm trying to import a win7 machine which works but then it never boots. I've tried removing as many drivers as possible, changing the controller, removing the network but the vm never boots. I've...

Solved: https://forum.proxmox.com/posts/606419/ Some time back, I upgraded my hosts to 8.0.3 and all seemed to be fine. All of sudden, I'm not able to migrate a host and keep getting the ssh key warning. I logged into both hosts that I wanted to migrate between and tried to ssh from one to the...

When I started playing with proxmox, I set very simple passwords on the hosts I set up. I then joined them in a cluster using the same bad password across all hosts. Now that I'm being a little more serious with this, I'd like to have better passwords but am not sure how to go about it. Do I...

Is there any chance that the console allows or will eventually allow cut/paste? There so so many situations where I have to enter huge long complicated passwords to get in via the console and pasting would be so much more efficient.

What's odd is that this is a centos 7 vm, similar to others that I've converted/moved to proxmox but for some unknown reason, on boot, it always goes to dracut. On the others, I've simply had to change the SCSI controller, add the network back in and change the OS type and they run right off the...

I'm using proxmox hoping to get used to it and maybe replace all the vmware stuff we're using. I've had a cluster up and running for some time now, months. Everything seems to be just fine but I feel like there is some maintenance I should be doing even if all is working right. Can anyone...

The reason I'm asking is because I was sure I came across a post several months ago that said the backup server could also backup vms on esx hosts. I recently started looking for that but cannot find it anywhere now so I assume no but I thought I should ask here.

I got to work this morning to find that all of the backups failed across 4 nodes. I read that 'backup is sparse means something like a VM that takes 100GiB of space, contains 50GiB of zeros and is not unusual, maybe related to thin provisioning. However, looking at the errors, it's not clear why...

UPDATE: Don't work on servers before you've had coffee :). I'm running a 7.2 cluster. All has been working fine for months and suddenly, I get an error of a backup not completing. I take a look from the CLI and notice that one node in the cluster no longer has its NFS shares. That particular...

I'm running 7.2. I exported a dual disk file vm but cannot start it on vmware. After backing it up, I used the following to convert the two disks into a single vmdk. # qemu-img convert -O vmdk -f raw disk-drive-scsi0.raw disk-drive-scsi1.raw c6-voip.vmdk When trying to start it using vsca, I...

I have a cluster with backups configured which stores the backups onto network NFS storage. I was looking at the backup server a while back and now am wondering what the benefit of it is? If I understand correctly, the backup server is built into a cluster but it could also be used stand alone...

I read this in the documentation. This has a downside though. If you want to do a live migration of VMs between different hosts, your VM might end up on a new system with a different CPU type. If the CPU flags passed to the guest are missing, the qemu process will stop. To remedy this Qemu...

Solved using comment #2 suggestion. After upgrading from 7.1.7 to 7.2.x, I started having problems. Whether or not I broke something is not the question, I'm sure I did something wrong or at least will blame myself. However, I'm stuck in a whack-a-mole situation of ssh being broken across...
