Strange XS7 Issue
-
I ran some updates on my XS7 host tonight. There were a few updates, and they all installed and I rebooted.
This is my test/lab XS setup, and I have one Mint machine running on it. Been running for weeks with no issues.
The XS boots up fine. You can access the MGMT interface with no issue. The Mint machine also boots up with no issues. However, if you try to access the Mint machine from the network, or try to access the network from the Mint machine, both the VM and the XS host itself totally drop off the network.
As long as you don't access the network, the XS and VM stay up indefinitely. Accessing the network from either direction freezes both.
Any thoughts on what this could be?

An XS update. Guaranteed.

Reinstall XenServer Tools on Mint.

Patient: Doctor, it hurts when I do this.
Doctor: Stop doing that. -
What @JaredBusch is saying is check to make sure there is nothing extra stored in
/var/patchbesides the applied folder.Also check to make sure your logs aren't piling up in
/var/log -
Reinstalling XenServer Tools did not help.
Again, this is my lab box, but I want to be sure it's just an anomaly and not something else going on. So in this box there is only 1 ethernet adapter.
From the XS host, I can do anything. Ping by IP, ping by hostname, wget, SSH into it, etc..
From the VM, I can ping by IP address, but that is it. Once anything else is attempted (wget, SSH) it drops the whole adapter off. Which also drops off the host, obviously.
I tried to install a Ubuntu VM, and it froze in the middle of the install. CentOS doesn't get more than 10% past its install.
I'm trying to decide if it's something with the adapter (hardware or driver) or something else that has just gone wonky.

Was the Mint VM running while you were trying to install Ubuntu?

No.

NIC driver issue maybe. Remove the nic and readd

<shudders> that would involve touching XS. LOL.

Isn't that how this started - because you touched XS?

Only in the acceptable way.
You know how they feel about not treating it as an appliance.
Oh no, I've already said too much...

FFS.
XS is not an appliance, that is XO.
XS is a hypervisor, you have to know WTF you are doing to fondle it.

Uninstall XenServer tools from mint and try mint without the tools.
Is XenServer installed on hard drive or USB?

he's beyond that at this point. If the Mint VM is shutdown, he can't install a new VM, it just hangs.
I agree, at this point, look to see if you can remove and readd the NIC.

From a little back and forth on the XS forums, it appears others are also having this issue.
And get this ... only affects Linux VMs. I installed a new Windows VM instance, and it works perfectly.
THAT is a head scratcher.

Have you tried using "Other install media" template to create new Linux VMs?

These things all worked perfectly for months. Something in one of the latest updates broke it.
