xen: PV spinlocks enabled
by Brian E. Lavender 25 Jul '26

25 Jul '26

Kernel says "xen: PV spinlocks enabled". This is in the guest host that I booted paravirtualized. I imagine that this is a reference related to the topic in Thomas Friebel's "Preventing Guests from Spinning Around" https://lwn.net/Articles/289039/ I long had the mistaken assumption that a paravirtualized guest had to have the same version of the kernel running. That hasn't been the case. Brian -- Brian Lavender https://www.brie.com/brian/ "There are two ways of constructing a software design.

Yeah, I too kinda I miss ifconfig - but, then, just a couple of days ago I had someone from my ISP tell I just 'Old-Fashion' and that I should get my children to help me out. No, she didn't get the up-sell she wanted and I did politely somewhat snap her head about that remark. Anyway, a few years back I had a similar dilemma and I found some decent YouTube videos on the subject of 'ip'. Videos are pretty much the how-tos these days. *--* *Let it be known that my mind is as quick, sharp and strong as a steel bear trap,* * and it is in no way my fault that it has been left out in the rain, rusting it beyond * *all practical use.too kinda*

Just to close the thread. I got a VPS, Virtual Private Server. I already rent an external web server with hostpapa and adding this "feature" only cost me $3/month. It has a static ip and I use ssh -R to set up the tunnels for inbound traffic. It comes with a naked firewall, and I still need to do that. But so far it does what I need and I can get a standard residential plan and be good. I've already been using systemd to maintain some ssh -R tunnels when I had my own ip. There are a few gotchas, but I have a couple of years of experience with that and it is pretty settled now. I'll just transfer that config to the new VPS. ---- TNX!

This thing still working? Test Test 123 I will have to start working on upgrading this thing. I tried upgrading before and it failed... I am not sure why it failed. Mailman 3 config is a little tricky. I cloned the VM when I attempted to upgrade and rolled back... -- Brian Lavender https://www.brie.com/brian/ "There are two ways of constructing a software design.

It turns out, my network router and connection are really old. I'm not sure what will be available in my zip. Does anyone have experience with Tailscale?
