I'm back with more problems :-), After running fine for 2 days, now the server with a fresh Proxmox v6 install has problems as well. This thread is about the same problem. I had a stuck linux VM and even a triggered reboot on the host failed due to not being able to unmount LVM volumes, only a...

What is new is that problems got worse, the whole dist-upgrade lead to at least 2 servers tilting after some time with ZFS pool errors. The VM start to freeze and only a complete host reboot cycle brings the VMs back online. The only host that seems to do fine is the new one that has been...

More Info: I bootet into the old Proxmox 4.4 kernel 4.15.18-18-pve and it boots without a problem, so it seems the problem is related to the kernel from PRoxmox v6. I've attached the journal. After some more tests, I can say that it'S not the kernel, but the initrd.img. I changed...

More info: After having started the system in maintenance mode, mounted the failing lvm volume manually to /mnt, the blkid doesn't show a UUID for the partition: Mount: sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,relatime) proc on /proc type proc (rw,nosuid,nodev,noexec,relatime) udev on...

Hi folks, I just upgraded my cluster to be able to integrate a new server that has directly been installed with v6. It worked out fine but one problem that shows up on 2 of the 5 servers. Here's a fstab that I will use to explain the problem: /dev/pve/root / ext4 errors=remount-ro 0 1...

Thanxs guys for the quick help. In the end you where right, I missed the checkbox in the hardware settings. I did some more tests now and it behaves as expected. Again thanxs a lot for the help To document for others: Enable Firewall on datacenter level Enable Firewall on host level Enable...

As a follow up. Disabling the pve-firewall and setting up the following rules does the job: iptables -F iptables -A FORWARD -i vmbr0 -d X.Y.Z.69/32 -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT # Allow established and related packets iptables -A FORWARD -i vmbr0 -p tcp -s t.u.v.w/32 -d...

Thanxs for the answers, though I'm still stuck. > Set individual VM network interfaces to firewall What does that mean? The interface has a regex pattern 'net\d+', my VM has tap100i0 which of course doesn't fit. Should it be the "net0" definition out of the VM definition? I tried to minimize...

Hi guys, I'm trying to setup some firewall rules to protect a VM, but I fail badly and don't have a starting point to find out why. The proxmox host has a public IP X.Y.Z.80 from the network X.Y.Z.64/26 The VM uses a bridged network and also has a public IP X.Y.Z.69 I already tried setting...

Thanxs a lot, seems I was not capable of finding it with the search. Regards Schnuffle

Hi folks, just wanted to leave a note. I'm using Spice for all my VMs and did not have any special problem using virt-viewer under my linux box. Now I got requests from colleagues which need access to the console as well to do some tests. For testing I installed the latest virt-viewer version...

Hello, I'm trying to set some firewall rules for a VM but they do not take effect Setup: Proxmox 5.1 Network: Bridge connected to public interface Problem: Firewall Rules on VM level don't take any effect INPUT Policy Datacenter: REJECT INPUT Policy VM: REJECT Additional Infos...

Hello, I've a 4 server cluster and on one server I've the already mentionend problem, that it does not boot anymore falling back to the grub rescue console. Setup: RPOOL - single disk offered by a RAID controller ( I know you should not use a Controller, reality thinks different sometimes )...

Thanx for the answer but that isn't a solution. The problem is that I get a vagrant test environement that is based on the virtualbox provider. Adapting it to another provider would be a major task as the setup is quite complex and we get updates every couple of weeks. I had hope that Nested...

Hi folks, I'm trying to setup a VM that is used to launch other vagrant boxes with Virtualbox as provider.What have I done already: So my first step was to activate Nested Virtualization, as described in https://pve.proxmox.com/wiki/Nested_Virtualization. Result: root@proxmox5:~# cat...
