how do you reboot your linux VMs in hyper-v?
-
OK now I've eliminated some drifting in RCT <- yes RCT. I've monitored both gen1 and gen2 vm for something like 12 hours. no drift in 12 hours of VM idling.
this doesn't solve the thing: issued a reboot. got a shutdown! but at least without timing integration services now clocks seems logic in the VMs. I think even @JaredBusch got issues with timing and constant time reassignments...
I've also rebooted the server from the closet, nothing strange in the reboot sequence: all ok with the hypervisor. I've a new win update. let's apply this. also let's check the "latest" HPE service pack from october 2016, maybe some driver is apparently ok, but requires update...
bah. I'm going to think it's me. I'm cursed w/ hpe stuff.
A last thing remains: enter bios disable power savings and CPU c-states and let's see... then I'll STONITH my self
f#@*$%!

latest news: my pc with hyper-v correctly reboots everything! everytime! vene without latest kernel/hyper-v stuff in VM!
definitively a platform issue. last resort: reinstall all.

Are you running Server 2016 on your PC?

It's windows 10, so yes, in theory, it is the same hyper-v stack.
Honestly the only thing I can think of is issues with ACPI with the cpu. I've even disabled any energy saving but nothing!
if I keep the VM idling too much it stops and not reboots... any VM. -
LATEST NEWS:
yesterday, after a number of tests VM did freeze at reboot command rather than shutdown. As a last resort I've chosen to format SD/rest bios and restart from scratch.
My installation procedure did not work anymore... hell 2 times was right the third has failed...
called HPE this morning, they have asked me to do some tests via Intelligent Provisioning. IP. chrashed with missing linux kernel file (IP is based on linux)
they will start mobo substitution procedures tomorrow morning.
F*#@ wasted 15 days.
15 D.A.Y.S.
ever seen a failing server MOBO? I've. And I've provisioned just 3 servers in my life!
-
@matteo-nunziati that sounds like a pain. Hopefully the issue is resolved after the changes.

Hope so :s

OK,
some news here after full rebuild of server.
MOBO failure was an extra, still VMs do not reboot.
well, not exactly...
we have installed some windows core, some ubuntu bare server, some windows full gui, some ubuntu server with full MATE desktop.
now the "barebone" VMs do not reboot, they just shutdown.
The full bloated VMs restart nicely!I think this is something to do with the speed of the reboot cycle... but even my reseller tech ignores what to do... HPE is finally thinking to pass me to L2 support.
project is delayed at least of 1 week wrt deadlines (and I've kept 1 extra week at the time, just in case)

BOTTOMLINE: NEVER NEVER NEVER BUY HPE STUFF EVERMORE!!!
ALSO CHECK FOR LOCAL XEN SHOP: THERE MUST BE ONE!
(yeah I know, we can have remote management, but company is not ready for this, they want sys admin cell phone and they what to touch sys admin like a sky-alighting divinity)

You can do that with a remote company too. But calling someone's cell phone isn't professional and introduces a single point of failure.

not my decision. I was going to settle with dell stuff with another reseller, offering help desk with SLA + 24/7 dell onsite. but they (company) wanted the sysadmin to be physical and periodically "visible"

I was only saying that remote companies can provide local resources. There is no connection between where a company is based and where their staff are based or can appear.

OK, just for the sake of statistics,
how many of you run hyper-v server 2016, I mean the Core version, without GUI.
how many run on HPE HW?thank you!

Used to, but not any longer. Moved to Dell.

We still have a lot of HPE. Starting to get more Dell though.

We are almost exclusively Dell here... and have been for a while... We still have a couple of PowerEdge 2950s that are in service (but soon to be retired).
-
OK,
new poll!
how many of you do change the default VM paging location?
BTW, what the hell is VM paging and how can be this of any use for linux VM?

so basically this is hypervisor provided swap, before vm inner swap!
-
and after a lot of episodes, I've fixed the thing.
please let me state this again: I HAVE.
I.
Not the HPE support, not the reseller tech support.
I HAVE.
I = An almost idiot ex-embedded sw developer illogically cast into the sysadmin role of a non-sense company!
TL; DR:
there was a mismatch between OS version, bios version, controllers firmware version, controller drivers version. Selecting the right combination has (apprarently) fixed the issue!how storage controllers affect reboot signals is still a mistery... but actually all was related to the smart paging I mentioned before. Moving it from the default location caused all the issues.
I have discovered the "bug" recreating a new vm with copy-pasted hdd but with hypervisor defaults... 2 twins VM one running one not... only difference: location of the smart paging file. XD
