I upgraded to proxmox 8 last night. All my VMs now can't get an ip adress from the dhcp server. Not sure how to troubleshoot this. Other appliances on the home network get ip addresses just fine.

I can't decide if its better to have a dedicated vm for each docker app install or just create one gaint vm to hold all docker containers ? Most of the discussions I have seen are centered on the merits of installing docker in an lxc or vm. I have decided to go the vm route. What are the...

I want to passthrough a dedicated 10G nic port to my truenas scale setup. I typically setup the static ip address by mapping a mac address to the static ip in my dhcp server. Not sure how this will work with the passthrough nic. I know the mac address of the NIC port. However, not sure where...

Hello I have a Dell R740 server which has a PCIe backplane extender for nvme drives. I am looking to passthrough the extender to a truenas install . When I go to add PCIe device for the truenas vm, I don't see the extender listed though I can see it when I do an lspci on the proxmox node...

I recently got a Dell PowerEdge 740xd which came with an enterprise lifecycle controller license and a boss card. I installed proxmox on a dell boss card. However, I am finding that I am not getting the full functionality of the lifecycle controller without installing an approved OS for the...

I have setup my management on vlan5 and eno1 port with the code below. The problem is, other vlans seem to be going through this as well. For instance, I am able to get vlan 20 to get an ip in the 20 subnet even if I use vmbr0. How can I restrict this to only vlan 5 ? iface eno1.5 inet manual...

I am looking to install a pair of kea-dhcp servers ( in ha mode ) on proxmox ubuntu virtual machines. I am getting myself confused about how the vms for the dhcp servers are assigned ip addresses during boot - since the dhcp server itself gives out the ip addresses. I suspect this is a noob...

I have a rather rudimentary question but can't figure out. Storage for my proxmox vms and efi disks are stored on my single synology server. The vms themselves are on an ssd drive on the proxmox server. However, every time there is a hiccup with my synology box, all the vms are not bootable or...

I am sure this has been asked quite a bit, but I dont quite understand it. I have a zfs pool setup on a disk I intended to use as a data storage disk for my containers and vms. ( not for images or backups ). On a container, I am able to use a bind mount. How is this done on a VM? I just...

I setup proxmox with ip 172.20.2.3 on a supermicro box with ip 172.20.2.2. I have a default linux bridge vmbr0 with a cidr at 172.20.2.3/24 and gateway of 172.20.2.1. I am thinking of changing all the above to the following: keep the supermicro box in the 172 subnet. So it remains 172.20.2.2...

I installed my proxmox server on a two 250 gb ssd with raid1. My vms are stored on another zfs storage pool. The box has 64 gb memory. My memory usage is constantly past 90% despite having a few containers and vms setup with about 30 gb usage between all of them. I am having to do this daily...

I installed proxmox using the legacy mode - setting the bios to legacy on my supermicro server. Is it possible now, to change to uefi bootloader for my proxmox host? Or do I have to tear everything down and redo?

Hello - I just added a local storage disk in my server. I'd like to setup a zfs pool on it - Please let me know if its possible to do all of the following on one zfs pool : create a partition for scheduled backups ( vzdumps of all containers and vms) create a partition for database storage -...

I am looking to use acme certificates with haproxy on my pfsense vm to offload /manage certificates on local clients - like my synology box. On a physical pfsense box, this is usually involves installing the acme and haproxy packages on pfsense. Now, with my pfsense virtualized in proxmox, I...

My proxmox install doesn't seem to see my cpu features. I have the X11SDV-8C-TP8F Supermicro board and Xenon 2146 cpu. My cpu supports aes-ni and its enabled in the bios. However, when I check for it on proxmox, its not there: I also installed a pf sense vm and nothing is picked up - even...

I am having a problem accessing my pfsense install on my proxmox host. I am showing the port is not active even though when I connect my laptop to it the dhcp server on pfsense assigns an ip address . The vm seems to be working but i cant access the pfsense gui. I have set my laptop to a...

I have been trying to setup 2 nics on my freshly installed pfsense vm with pci passthrough. I have gone through all the guides and set things up as directed. Nothing seems to work. As soon as I try to start the pfsense vm for the first time, the whole host goes down - I have to delete the vm and...

I am getting myself confused with how to add storage on a separate local disk ( disk 2 ) to my containers - which live on another disk. ( disk 1) For example, I have setup a container with zfs on disk 1. This is for a postgres database. I'd like to store the database itself - not the...

I tried updating a new install from: deb http://download.proxmox.com/debian buster pve-no-subscription Got an error message below and now cant boot at all into proxmox . Any ideas how to fix this? There are no other lines of code in the sources.list except the one above.

Anyone setup a data science environment on proxmox? Something akin to the data science machine you can roll on azure ( azure data science vm ) Is there an image for something like this or something close to this? use a vm or container? my VMs are on a single ssd drive. I am planning to...
