I have a fresh install of prxmox VE 6.8.4-2-pve . physical machine is connected to a trunk on my switch in lacp ( i have also tried single port). i can assign vlan 100 to the host and have no issues connecting to it, but my debian12 vm cannot get network access. I can ping from host to vm and vm to host sometimes. When i installed deb12 i could not connect to APT, during the install i can ping the IP of the new install up until it tries to connect to APT for software selection, after that the network stops responding until you get the apt error page. Once apt times out the vm will ping until you try APT again..

Another time, as soon as grub loads on the VM the network will respond to pings from another device on the LAN but as soon as the login appears it falls off the network.
Here is my config below

also if i put any vlan on the host it will work perfectly fine, just not on any VM


HOST

Code:
auto lo
iface lo inet loopback

auto eno1
iface eno1 inet manual

auto eno2
iface eno2 inet manual

iface bond0 inet manual
        bond-slaves eno1 eno2
        bond-miimon 100
        bond-mode 802.3ad
        bond-xmit-hash-policy layer2

iface bond0.100 inet manual

auto vmbr0v100
iface vmbr0v100 inet static
        address 10.10.100.10/24
        gateway 10.10.100.1
        bridge-ports bond0.100
        bridge-stp off

auto vmbr0
iface vmbr0 inet manual
        bridge-ports bond0
        bridge-stp off
        bridge-fd 0
        bridge-vlan-aware yes
        bridge-vids 2-4094
