I can not find yum install xcp-ng-updater in the blog post at you mentioned try yum update

@TheFrisianClause
I did yum update and it worked. See if this post provide any clue? https://community.spiceworks.com/topic/2165339-yum-update-not-working-after-disabling-ipv6

xe vtpm-create vm-uuid=UUID_OF_YOUR_VM

was enough to enable the vTPM in my case. Thank you so much.

How to add vTPM in Xen Orchestra?

I have XCP-ng 8.3 beta and XOA 5.83.3

@xTITUS-MAXIMUSx

Thanks for the tip. I went to the bios and enabled the Intel Virtualization Technology and I thought I was done. After further research I recognized there are two steps to Enable the Intel Virtualization Technology. https://us.informatiweb.net/tutorials/it/bios/enable-iommu-or-vt-d-in-your-bios.html

• Advanced >> CPU configuration >> Intel Virtualization Technology >> Enable
• Advanced >> System Agent Configuration >> VT-d >> Enable

I do not see mt WIFI card in my VM

I am thinking I need to pass the WIFI card PCI to my VM. So, I have ASUS H110T motherboard and I am trying to get M.2 wifi card be recognized by the VM. I followed the instruction here https://xcp-ng.org/docs/compute.html. I enabled the Virtualization in BIOS. SSH to xcp-ng.

I am interested in passing-through the 02:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32) I followed the instruction.

# /opt/xensource/libexec/xen-cmdline --set-dom0 "xen-pciback.hide=(0000:02:00.0)"
# reboot

The WIFI card was excluded.

# xl pci-assignable-list
0000:02:00.0

then I added the PCI to the VM but I am getting an error. This is the third time I am doing this the first time there was no error but I could not see the WIFI card in the VM either. Any suggestion on how to solve this error ?

I am back to the office and I am troubleshooting different settings and connection setups. I appreciate all your input. The issue is configuring the right NIC0/NIC1/WAN/ and LAN. Once I am done I post my setting. Thanks again for everyone.

how have you configured the network for your vm?

@HeMaN I set everything to go through pfsense. Hence, the openwrt VM WAN is connected to static IP from pfsense 192.168.30.12. The openwrt VM LAN is 192.168.20.1/24.

first create a network connected to a physical nic and use that as wan for openwrt
then create en internal network (or use another nic) and use that as lan for openwrt.

@HeMaN Thank you for the tip. Just to make sure I understand correctly. I already have WAN and LAN networks for each NIC. But for some reason only the LAN is recognized by the Openwrt and I can not connect to the internet when I am on the LAN. I think it is a network issue this is why I decided to just follow the guide.

ps what is the use of openwrt when you already have pfsense?
both are basically routers
I love pfsense but the OS but the WIFI support lags behind. I am planning to use openwrt for WIFI access.

I have a small PC that I was using as a pfsense router/firewall. I wanted to add WIFI capability to the unit. I tested openwrt on the current hardware and it worked. Now, I virtualized the pfsense (working) and I would like to add the openwrt. There are instruction on how to install openwrt on Xen https://openwrt.org/docs/guide-user/virtualization/xen and I though this may work on xcp-ng but I need some help.

• I am not sure where to place the domain configuration file Xen-OpenWrt.conf

• I am assuming the network configuration is done at the xcp-ng terminal, right?

brctl addbr owrt-lan
ip link set owrt-lan up
ip addr add 192.168.1.42/24 dev owrt-lan

brctl addbr owrt-wan
ip link set dev eth0 up
brctl addif owrt-wan eth0
ip link set owrt-wan up

• Where to find the Xen domain configuration file?

Please note I have no IT background but I love tinkering. Thanks in advance for your help and input.
