Proxmox as ESXI guest

[gtrovato]

Hi All,

I've a trouble with Proxmox installed on ESXI.
I was able to run Proxmox (6.2.1) as ESXI guest.
But on any Proxmox guest the network doesn't work.
I've set VMBR bridge: guests can ping to Proxmox IP but not to others IPs (external to Proxmox).

Any hints?
Is it a problem due to nesting?

Thank you!

hi,

i don't think so. probably it's just a networking misconfiguration.

* can your PVE host reach the outside internet?

* you can post the /etc/network/interfaces from your PVE host

* and the network configuration of your guest

Thanks for answering!

I've tried with Ubuntu 20.04 and 18.04, configured with NIC connected to all VMBR, in DHCP (but it doesn't acquire IP) and static (I've different LANs on each VMBR with DHCP server).
The host reaches Internet and his LAN (192.68.3.0).
Ubuntu guest can ping Proxmox (192.168.3.30) but no the gateway (192.168.3.254) or other devices on LAN.
So it seems a problem on bridging.
I've the same setup working properly with Proxmox on a physical server.

auto lo
iface lo inet loopback

iface ens192 inet manual
iface ens224 inet manual
iface ens256 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.3.30/24
gateway 192.168.3.254
bridge-ports ens192
bridge-stp off
bridge-fd 0

auto vmbr1
iface vmbr1 inet manual
bridge-ports ens224
bridge-stp off
bridge-fd 0

auto vmbr2
iface vmbr2 inet manual
bridge-ports ens256
bridge-stp off
bridge-fd 0

could be also a routing issue
what about the network config inside the VM?

* ip a && ip r
* /etc/network/interfaces (or whichever network tool you're using)

hi,

have you checked if you enabled 'promiscous' mode for the network interface in esxi? (to allow mac spoofing of guests)
