Enabling IPv6 SLAAC removes all IPv4 VM connectivity

$

0
Hi,

I've been trying to configure IPv6 on my Proxmox V8 host. Everytime I enable my IPv6 config, all of my virtual machines lose connectivity, despite having ipv6 disabled (with net.ipv6.conf.ens18.disable_ipv6 = 1).

My server provider provides an IPv6 SLAAC configuration which i've tried to enable with this interfaces file :

Code:
auto lo
iface lo inet loopback

iface enp1s0f0 inet manual

iface enp1s0f1 inet manual
        mtu 9000

auto vmbr0

# Public IPv4 network
iface vmbr0 inet...

Hi Everyone, could you please give an advice how to configure my network? Looks like I got stuck.

I have Proxmox server and I install OPNsense firewal as a VM inside PVE. After that I passthrough a 2 NIC PCIe network card derectly to the VM. OPNsense (firewall) work perfectly with all productivity I need.

However, now I am little bit confuse and have no clear view how to do with rest of the VM, PVE, etc. Thereis really lots of options, even just connect port of the PCIe, which is LAN...

Hi all, im pretty new to servers and networking so don't know much yet. I added a new TP link router into my network making my ip adresses go from 192.168.0.___ to 192.168.1.___.

Windows can't see any drivers after loading Win11 VirtIO drivers

For some reason when I add the viostor>win11<amd64 folder (or the entire drive, viostor folder, or viostor>win11 folder) Windows doesn't find any compatible drivers. It can see the Red Hat drivers if I uncheck the box to display incompatible drivers, but adding those doesn't help. Can anyone see what it is in my configuratio0n that is preventing me from using any VirtIO drivers and progressing the install?

Hello everyone!

I have a PVE (not in cluster), installed in the "default" mode, with EXT4 and LVM and, at the end of the installation process, in the first access, I remove the "lvm-data" partition and resized the root volume using:

Code:
lvremove /dev/pve/data
lvresize -l +100%FREE /dev/pve/root
resize2fs /dev/mapper/pve-root

I have VMs and CTs, stored in the "local" storage, but only VMs can do snapshot backups. I have CTs with and without bind mounts and none of them can do...

Hi. I finally bought one for my NAS server but I can't activate IOMMU for passthrough. Company claim that IOMMU and AMD-VT activated by default. In bios firmware there are no such option(or may bi. But all manipulation with Grub that I do with previous mb with Ryzen and Proxmox 8.1 don't work.

May be someone completed this quest or have fresher firmware. I have version from May 07, 2024.

Ceph-equivalent of a qdevice in an even numbered split cluster

Hi,

we have an even numbered cluster stretched over 2 buildings, we're using Size 4/2 with a custom crush rule for placement of 2copies in each building.
Everything works great, one side could die due to power issues etc. and in that situation we'd still have 2 copies up and Ceph could work in the surviving site.

But losing one side still causes Ceph to stop working because the Ceph Mons don't have quorum.

Regarding Proxmox Cluster/Corosync, qdevice as external voting mechanism is the...

Hi, I'm new - maybe someone can help. I've decided to install and set up a mail server, but I don't know where to start! I've set one up from scratch - unfortunately without backup and everything is gone again! I used iredmail there which I think is user-friendly.. does anyone have templates lxc container images/scripts/templates for iredmail or do you have another idea for a mail server?

This is just a lab environment, I have 2 PVE, PVE1 is using sshfs to mount backup storage on PVE2 to backup CT to other host. Now I want to restore the backups from PVE1 to a CT on PVE2... no matter what I do I keep getting an error that it cannot create dirs or storage out of space, which has even happened on a nearly empty 500gb SSD, I created a new 16GB debian CT on that SSD fine, but restoring to it fails, doesnt matter if its dir storage or block.

VMs failing to start and migration.

$
0

I have a Proxmox cluster with 3 nodes (Node 1, Node 2, and Node 3). Node 2 has been offline for some time, and I suspect the issue is related to storage, as the node shows a grey question mark with 98% storage usage. Today, Node 1 restarted, and as a result, VMs were automatically migrated to Node 2. However, the VMs on Node 2 also became greyed out, and I can no longer access Node 2 via the GUI.

To work around this, I manually migrated the VMs from Node 2 to Node 1 using the mv command...

My Minisforum MS-01 finally arrived after 4 months so I've spent nearly 24 hous trying to see if I can get iGPU passthrough to work, no luck so far. I'll detail my settings and results so far and see if anyone can comment. Hopefully this thread will end up with a working example that can apply to all MS-01s with Xe gfx. I'm only interested in a Linux guest (CachyOS FWIW) but I'm happy to test Ubuntu/Debian/Win10 if I have any success with a CachyOS guest VM.

Question about file system

Hi All,

Relatively new Proxmox user here, so I apologize if this comes off as an uninformed question.

Back when I spun up proxmox (single NVME ssd, micro PC), I selected ZFS (RAID 0 as I only have one drive) for the file system. At the time, I thought that was a good idea. After doing some more research over time, I'm reading a lot about the wear/tear on consumer grade SSD's, which is exactly what I have.

I am concerned about the risk of failure of my current SSD and wondering if I...
