This is relating to PVE 6.2 I update my nodes relatively frequently and obviously keep an ear open for important updates that might mean an update needs to be done sooner rather than later. Today I had expected to need to install a grub2 update along with the associated bits and bobs, but...

For those of us with no experience of this....could you post further details please?

Well, although I said GUI here, I didn't specify it in my original question. I don't think it should matter. All the gui does is call apt-get dist-upgrade. I think the implication was that if something was updated that needed to be restarted (e.g. the gui itself or qemu-server or whatever) then...

In a different post, I was told that after an update via the gui, any services that needed a restart would be automatically restarted.....hmmm....

Thanks infra. That makes sense to me now and I have a great starting point to explore further.

See https://www.cyberciti.biz/faq/howto-copy-mbr/ (Linux sfdisk example a little down the page) and also https://www.cyberciti.biz/faq/linux-backup-restore-a-partition-table-with-sfdisk-command/ I have made copies and stored them safely. Having said that, examining the copies in a text...

Thanks @LnxBil and @fabian I had forgotten that the qemu-agent was of course installed in all VMs and assisted during backups. And I didn't realise that pbs backups of VMs would/could use a similar snapshot technology to vzbackup. I exclusively use Centos 7 in all VMs (Centos 8 too in the not...

Is there any special handling of mysql databases required when using PBS to backup VMs via PVE? Keeping in mind that I'm no mysql expert (and not a backup expert either!): With Acronis backups, which need a client installed in the VM, a freeze script is launched that I think freezes mysql...

I don't like the sound of this at all. I cannot trust a system where performing a backup or restoring a backup can potentially cause data loss. This kind of thing stops me sleeping soundly. We absolutely must find out what the root cause is. On the positive side, I've restored backups from...

Ah! Unfortunately my non-production setup has to mirror my production setup (pbs being an exception because I couldn't wait to test!) so that I can test updates in the lab before pushing them to the production machines. So I will simply have to be patient and await their appearance in the...

I'm having some interesting problems with the beta. Essentally, when I run a backup via PVE, the VM crashes and I see a segfault in the host node syslog. Here's what I did: I have two nodes in a cluster, both with local storage only. In PVE, I created a VM and installed PBS from the ISO (all...

I'm very glad you figured that one out. I would never have managed it. All my systems use separately defined network subnet etc too. But I thought ifupdown2 was only for the sdn feature, which is in beta? Something to do with rebootless network changes? Or maybe I'm mixing things up/getting...

Its possible that the Proxmox firewall is preventing access from IPs not on the local network. Maybe check that? But otherwise I can't think of anything other than the router not correctly port forwarding for some reason.

I'm not sure I understand your question. When you say external, do you mean from the internet? Of from your LAN? From your LAN, you'd just login to the Proxmox GUI and from there choose one of the console options, including VNC, which is why I'm confused by your question. The VM's get DHCP from...

You need to configure the network settings in the Centos VM itself. Proxmox cannot set them (unless you happened to use a cloud-init image). During Centos installation, did you enable networking and set up a public IP? In the Centos VM, check /etc/sysconfig/network-scripts/ifcfg-eth0 as this...

In case it helps, I'm not seeing it on my Dell R310 testbed systems. Intel(R) Xeon(R) CPU X3470 @ 2.93GHz They have no significant load though. Just Centos 7 test VMs doing absolutely nothing. I've backed them all up multiple times though, rebooted them, suspended them etc, just to see if I...

@SnowFox can post info on the CPU in your system please?

Thanks Wolfgang. With that knowledge, I did some more experimentation, but to no avail. But after installing this week's new kernel in the VM and doing a reboot, the problem has mysteriously gone away. Unfortunately I don't know if it was just the reboot or if it was the kernel that resolved...

This may have nothing to do with PVE, but I thought I'd better check anyway, because I'm getting really confused. I have some Centos 7 VMs where I can't load the overlay module using "modprobe overlay": modprobe: ERROR: could not insert 'overlay': Operation not permitted I can't see anything...

When you say "The server side is standalone, but client side is fully integrated", does this mean the server cannot be installed on a Proxmox node? (I mean natively, alongside Proxmox and not in a VM or CT). EDIT: I see that it can, but it is not recommended. Anyway, this is very exciting and...
