Re: [bitfolk] Upcoming reboot for security patch, XSA-212

One of the hosts that was being rebooted is also one of a pair of routers for our IPv6 traffic, and it happened to be the one that was active at the time. If/when it goes down it should automatically fail over to the other one, but I decided to manually fail it over to make the work simpler. Unfortunately it seems that when that happens, it also disables IPv6 for all of the VPSes on the host itself (hen). This was unexpected and took me a few minutes to work out what had happened. After approximately 9 minutes I realised the problems were restricted to v6 for VPSes on that single host, and I was able to restore their v6 connectivity. Of course, by that point it was time to reboot the host anyway. So, customers on host hen unexpectedly experienced approximately 9 minutes of no IPv6 just before they expectedly experienced it all being rebooted anyway. Sorry about that! It is likely I never noticed that issue before because it would have only happened when the host was down. Other than that I noticed no suspend-and-restore failures, and there were only two pvgrub booting problem that I noticed. The first one was similar to the others seen, which involved Gentoo and pvgrub complaining that it can't load the kernel. That customer, like the others, was reverted back to pygrub and I will need to do further testing. The other one appeared to be down to the customer having a 64-bit kernel without telling us, so it wouldn't boot with 32-bit pvgrub. Switching them to 64-bit pvgrub allowed it to boot. I will discuss that with the individual customer, but as a reminder: if you have a 64-bit kernel, we need to know. For a couple of years now all new installs have been 64-bit, but if you have been a customer for longer than that you probably started out as 32-bit. If you've changed it to be 64-bit we need to know otherwise your VPS won't boot. You can tell what we think it is by looking at the summary page of the Panel: https://panel.bitfolk.com/account/ If it says "/ i686" then we think it's 32-bit. You can also tell by logging in to your Xen Shell and typing the "arch" command. You can tell us it is something different by typing either "arch x86_64" or "arch i686" in the Xen Shell.
