Hello,
It's a bit a theoretical question, because I don't manage virtual machines at the moment, but I just noticed one of my host vendor do provide several IP for cheap servers, and this may be very handy to have virtual machines (http://www.soyoustart.com/fr/offres/e3-sat-1.xml).
I see theses days a lot of kernel updates. For what I know, updating kernel needs rebooting.
but rebooting a *host* means switching off then on any virtual machine, ins't it?
Yes.
on the same time, I see some servers with uptime of one year and more.
per@kzinti:~> uptime 08:13 up 1168 days 23:42, 1 user, load average: 0.00, 0.04, 0.10
so my question: how do you manage the security of servers acting as host for, say, 10 virtual machines.
Surely not a topic for opensuse-factory? Anyway, my xen hosts simply have no external connectivity. Second, when a xen host needs maintenance, we migrate the DomUs off to another host.
any pointer to answer on the web welcome :-)
