@JonathanLee Yeah maybe a virtual router. I'll consider that, Thanks for the advice.

go to the proxmox forum

@tibere86 Please create a new post for your question. Thanks.

@Richard-1 said in No DHCP on proxmox: On my Win11 VM I receive ip configuration from DHCP server, on my physical PC no DHCP configuration received, I need to enter ip, subnetmask, gateway, ... manually to connect to network. It's the way you have it setup...please see here: https://docs.netgate.com/pfsense/en/latest/recipes/virtualize-proxmox-ve.html Did you connect your physical PC to pfSense LAN? Nothing is wrong to connect manually though. You should consider amending your title as Proxmox doesn't do DHCP.

@thebear 2 vCPUs and 8G memory.

@raqib But it is not helping in every case, I had problems on Server 2022 and this only helped some of the time. What "helped" me all of the time was using two separate, external vSwitches, one only for pfSense and one for all the other VMs. And that meant there had to be a physical switch in place to connect those two vSwitches. Thankfully it is working in the latest Plus-version.

So, I found a GUI "bug". I had correctly set the prefix ID's in the "Tracked Interface" for each VLAN, but at the RA page, I mistakenly reinserted the prefix ID in the fields that are for static (full, not delegated) prefixes. Removed the static prefixes and everything now works. GUI should not let you enter static prefixes on a tracked interface, aside from fc00 or fd. And if it does, it should check if they are correct. One of the prefixes was ::1/64.

Proxmox with a FreeBSD guest Proxmox recommends using ntpd daemon in a FreeBSD client to maintain client real time synchronization. See pve.proxmox. com/wiki/FreeBSD_Guest_Notes and forum.proxmox. com/threads/time-drift-in-windows-7-guest.41268/#post-198848 Real time is set in the guest when it first starts. After which the guest clock drifts with the hosts processor crystal. ntpd is the ntp daemon. See www.freebsd. org/cgi/man.cgi?query=ntpd&apropos=0&sektion=8&manpath=FreeBSD+12.2-stable&arch=default&format=html Configured via /etc/ntp.conf Command line interface ntpq See www.freebsd. org/cgi/man.cgi?query=ntpq&sektion=8&apropos=0&manpath=FreeBSD+12.2-RELEASE+and+Ports 11 minute hardware real time clock update can be enable by adding the line "SYNC_HWCLOCK=yes" to /etc/sysconfig/ntpdate date gives time of day to 1 second resolution Qemu guest agent I think qemu can also sync time between the guest and Porxmox host. Doing so is suggested github. com/aborche/qemu-guest-agent/blob/master/supported_command_reference.md Other virtualization systems such as vmware have time synchronization between host and guest via the agent Time synchronization should be done via only one system otherwise interaction between them decreases time system accuracy. Which mean if an agent and ntpd is used then there would need to be a way of disabling time synchronization via the agent. I'm not sure how to do this. pfsense guest on Proxmox host Given it is probably best to run ntp (chrony) on Proxmox then synch time in pfsense to the Proxmox host via ntpd over the LAN interface. Ideally I would like to do the following but not sure how to acheive that in pfsense Enable ntpd on pfsense but not listening to clients on any interface. Selecting no interfaces in the GUI does the reverse. Disable hardware real time clock update by pfsense. This is done every 11 minutes by chronyd on the Proxmox host. In pfsense the directory structure is different, so I can't goto to /etc/sysconfig/ntpdate and set SYNC_HWCLOCK=no

And how does ESXi 7.0 install relate to pfSense ? You ought to do a better 1'st post. Btw: 7.0 removed the linux subsystem , rendering ALL realtek-drivers useless. /Bingo

@maverickws have you checked iperf3 speeds between pfsense and xcp-ng itself? Mine is bad. Additionally from pfsense to xcp-ng it has many retries during transfer

sorry to necro this but its the top google search for the topic - do you have any insight into performance difference between KVM vs LXC QEMU? it would be nice to get a definitive answer on which is better

Problem solved. You need to set "Westmere" or "kvm64" CPU type instead of host passthrough in libvirt/virsh/kvm/qemu configuration file "virsh edit $vmname" <cpu mode='custom' match='exact' check='none'> <model fallback='allow'>Westmere</model> <topology sockets='1' cores='6' threads='2'/> </cpu>
