Hi currently running xcp-ng 8.2 and within my small form factor I have 4 VMs. One of the VMs is currently virtualized pfsense. When xcp-ng boots I'd actually like the pfsense VM to start first. Is it possible to assign in XO or through the xcp-ng CLI itself the proposed boot order of the various VMs?

Hey thanks for working on XCP-ng Center -- I find it a really useful tool.

Is this a README that describes how your project differs from XenCenter.

Hey do you have actual instructions on how to compile from source? I trying to work with someone creating an arch linux AUR package and was looking for a little more input.

FWIW -- I had a similar problem with VMs going randomly down -- it wasn't windows but various BSD and Linux VM's. Sometimes they would run a few days, other times they would lock up every other day. Logs didn't help because when the VM locked, logs were not written. I even had the xcp-ng installation lock a few times, although it was usually on of the VMs. I started searching for faulty hardware and eventually SMART tested all the drives and mem86 the RAM. Turns out I had some bad RAM modules which I later RMA'd. With new RAM (after after thoroughly testing it), I haven't had any lock ups. I'm not sure this will help you at all.

@julien-f Thanks for explanation. Thank you

@olivierlambert

Well damn -- you're right.

Well VM now up and running. Just have to figure out how networking works in this new copied VM. Thanks for help.

Not that you actually needed this reply, but confirmed patch works after upgrade this morning.

Thanks for update and the patch.

@nikade Hey thanks for for the link. I ended up just using a LetsEncrypt cert rather than self signed. I think had to add a DNS host override on my router to associate the Local LAN address of the xo server with the domain name of the server contained in the certificate -- Like 10.0.1.50 ---> xo.example.com. Thanks for pointing me in the right direction on this one.

@DustinB I have time to run a ram check (luckily), and if not I'll just recreate VM. Luckily pfsense makes it pretty easy to reinstall from scratch by saving to a configuration file which can be imported to new version. I'll work on it later today or tomorrow and report back.

I'm running pfsense version 2.8.0 virtualized on xcp-ng 8.3.0.

The host has 64 GB RAM (two 32 GB dual channel DDR4 modules) with a 1Tb Nvme drive and 1tb samsung SSD.

I have 5 virtualized systems on the xcp-ng host consuming a total of 30Gb of the 64 GB.

One of my virtualized hosts is pfSense 2.8.0. Recently the pfSense host is giving me consistent error messages such as the following:

Aug 25 07:46:28	kernel		vm_fault: pager read error, pid 24443 (rrdtool)

Doing some reading on the error (https://www.reddit.com/r/opnsense/comments/1jlfshn/vm_fault_pager_read_error_pid_76098_rrdtool/), it could indicate a bad RAM module?? I'm just not sure. Is RAM presented to the pfsense host as virtual memory? Other than doing a mem86+ test on the RAM modules of the xcp-ng host, is there any other way to debug this error? I don't see errors from any other of the virtualized linux operating systems, however is there something I should be checking on the other virtualized systems or the host that would confirm a possible memory error as error (assuming its a memory error)?

Thanks for any input.

So I managed to build with Cargo on arch (which also required clang as a dependency). Moved xen-guest-agent/target/debug/xen-guest-agent to /usr/sbin and also copied the basic xen-guest-agent/startup/xen-guest-agent.service file to /etc/systemd/system and enable/started the service.

And ahh -- success --

I guess my project for week is to figure out how to write a PKGBUILD file for this particular project. We'll see how that goes

I'm assuming since building from git repository (https://gitlab.com/xen-project/xen-guest-agent) there aren't going to be any file signatures to check against. I'm looking at cargo, clang, python-setuptools and xen as dependencies?

When using this toolset, what network interface names does this match against? For example it will match against interface names starting with eth and I think enpS. I looked in the source code within the main branch but couldn't find the file where this search occurs.

@gskger Why don't you install acme.sh or something similar on XO host and deploy from there. No need to use pfSense.

@yann Yes I tried compiling with cargo. Got along some of the way until I reached this:

  Failed to locate xenstore library:
  pkg-config exited with status code 1
  > PKG_CONFIG_ALLOW_SYSTEM_LIBS=1 PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=1 pkg-config --libs --cflags xenstore

  The system library `xenstore` required by crate `xenstore-sys` was not found.
  The file `xenstore.pc` needs to be installed and the PKG_CONFIG_PATH environment variable must contain its parent directory.
  The PKG_CONFIG_PATH environment variable is not set.

  HINT: if you have installed the library, try setting PKG_CONFIG_PATH to the directory containing `xenstore.pc`.

Where do I get the xenstore library? I've searched the AUR and pacman official archives and I can't seem to find.

Hey do you have actual instructions on how to compile from source? I trying to work with someone creating an arch linux AUR package and was looking for a little more input.

@olivierlambert Hey thanks a lot for that tip.

@Andrew Your link doesn't really address the question. xoa would be the username and the password is the same as what was setup during xoa creation -- or as your link helpfully pointed out -- you could reset the xoa system user password and go from there.

I need to become the root user in xoa. What is the root password? I've tried root/root but it doesn't work and it isn't in the documentation. I need to change the network interface for xoa.

@Danp Aww. see that box. Let me look into this problem a bit more. Learning some new things here.
