I tried a full shutdown. I let it go full "red" before clicking the start icon. XO is still reporting very different MAC and IP assignments from what the guest OS has configured. Is it perhaps due to the tools that OPNsense packages?

I have my router (OPNsense) running in a VM on XCP 8.2 and there seems to be a disparity between what XO is reporting from the guest utils and what the guest OS itself is saying.

In the guest OS, interface with MAC ending in 72:1e is my WAN interface, getting a DHCP address from my ISP. In XO, that interface is a static IP.

Here are two example interface assignments in the guest OS:

Here is how each of those is configured:

Here is how XO is reporting them:

That interface with the Jumbo Frames configured should be a 10.10.10.X address, per the OS config. That 192.168.5.X is on a completely different interface in the OS, and the MAC X:X:X:X:72:1e should be having the address currently shown on X:X:X:X:fd:93

Any suggestions? Because resolving networking issues when I can't get the information sources to align is problematic.

Thanks!

I have a couple of networks created for VLAN tagging purposes. These networks show on the Pool networking tab. They also appear on the two hosts that aren't the master. They are missing from the master node's network tab. Now, I can't migrate any VMs that have interfaces on these networks to the master host.

Is there a way to recreate those networks on just the one host? Being the master that is missing them, I'm afraid they'll disappear altogether at some point and those VMs will have issues.

Thanks!

@olivierlambert Fair enough. I will bring the disk for this VM onto the local SR for patching and rebooting my file server that hosts the NFS SR, just to be on the safe side.

I was hoping I could minimize the downtime by live-migrating the disk onto the host running it, but get the same error about PCI hardware as if I were trying to migrate the whole VM to another host.

But as far as you know, there is no technical reason for why it wouldn't work, like there is for live-migrating between hosts with passed-through hardware.

I have a VM that has a GPU assigned via PCIe passthrough, with its disk on an NFS SR. I understand why I can't live migrate a VM that utilizes PCIe passthrough.

But what is it that prevents migrating just the virtual disk to the local SR on the host running that VM?

@Darkbeldin I wasn't sure about turning on two-factor. I went through that process and generated the "app password" and it seems to be working.

Thanks for the info!

With Google essentially shutting off "less secure app access" in May, is there anything on the horizon for the email plugin to still function with Google's SMTP? I noticed my alerts stopped working, and when I checked my Google dashboard for the account that sends the alerts, Google had shut off the "less secure 3rd party apps access" automatically, and turning it back on was accompanied by a warning that it was being turned off permanently on May 20, 2022.

@Danp No, but I seem to have figured it out. Its a weird one, considering the platform.

These are HP DL360s, with fully licensed iLOs. But ... the CPU errors are gone if I physically connect a keyboard to the server. If I reboot just monitoring via remote console in the iLO, I get the errors. If I go to the machines and connect a USB keyboard before the reboot, then go back to my workstation and do it all through XO and watch via remote console, they come up fine. My post earlier about two coming up fine, I remembered that coincidentally, I'd switched the KVM to them.

So just an FYI to anyone who might have the same problem, plug in a keyboard.

@stormi Yeah, I spoke too soon. Two of my hosts came right up fine after the patches. The third has been in a boot loop with CPU panics and fatal page faults.

@stormi

Just as an FYI, the latest patches - 20190314-2.xcp - seem to not have an issue. The system patched and booted up just fine with no issues bringing up CPUs or anything like that.

@stormi I'll try that. If I update via CLI, I think I can use "yum update --exclude=microcode_ctl*" and see what happens. If I remember correctly, it was stating 22 patches missing when I started this process with the patches released last week. Now the fresh install is stating 43 missing patches.

@stormi I got a new master, and recovered the other slave. I did a fresh reinstall of the 8.2.0 ISO and the host came up just fine. So there's definitely something in the new code that breaks these machines.

@stormi I guess I don't know how to do that. Using the console "Resource Pool Configuration" -> "Designate a new pool master" results in a "This host is not a Pool member" message for both nodes.

Edit: I found an older post with the xe commands for emergency transition.

@stormi Even using the old kernel, I get issues booting. I'll try using my original install media to see if it will boot from USB. The problem I am having is that this is my master node, and I can't get another node to become master and get control of my VMs. Another node isn't becoming the new master for the remaining two nodes.

Update: Booting to the 8.2.0 install ISO, it booted into the installer just fine.

@stormi

The problem is, the system won't boot. It gets to that error and immediately just reboots. I got a screenshot only via the iLO remote console and having my finger on the printscreen key ready to grab before it went back to POST.

@thenorthernlight

I am at the latest I have access to, which is P71 05/24/2019 ... and near as I can tell searching HPE Support, that is the latest available. If there's a later one, I can't find it.

I installed the patches that were posted just a few days ago, and now one of my nodes is having an issue with CPUs.

These are HP DL360 G8s with Xeon E5-2690 v2 CPUs.

At the point in the boot when it applies microcode, it will seemingly randomly have an issue with "bringing up" one of the CPUs and reboot.

Sometimes its CPU 1, as in the attached screenshot. On another reboot, it might get to CPU 12. The next time around, only to CPU 5. I have tried disabling hyperthreading, just to reduce the possibilities.

I don't know what "error -5" is and I can't find anything online about it.

The two attached screenshots are the same host, different cycles through rebooting.

Anyone have an idea of what may be at issue?

Thanks!

I installed netdata on my hosts using yum, and everything went fine. Except there are missing collector confs. The Netdata documentation implies there should be a lot more in /usr/lib/netdata/conf.d/python.d than there are.

In particular, I have a need for the hpssacli collector to monitor disk on my four DL380s, but it isn't present in the XCP netdata install.

What would be the best way to go about getting additional collectors?

@olivierlambert Hmm ... well, I ran an update to XO, and the versions didn't change, but the upgrade allowed the restore to function. Now, unfortunately, it seems the backup is bad and won't mount /dev/xvda in r/w. Booting to an ISO and running e2fsck reports bad superblocks and can't recover anything. I guess I'll go back one more version and see if the one from the day before is functional before I am forced to just rebuild the server.
