xm/xl shutdown does not work with HVM guest

xm/xl shutdown does not work with HVM guest

[Saurabh Mishra]

[-- Attachment #1.1: Type: text/plain, Size: 793 bytes --]

Hi,

I'd like to know what should be configured in the HVM guest such that it
accepts 'xm/xl shutdown' graceful shutdown signal.

'xm/xl shutdown' works great when I have xen_platform_pci=1 (PV on HVM)
however whenever I disable xen_platform_pci=0, it does not work.

I also tried 'xl/xm trigger <vm> power' and this too does not work if
xen_platform_pci=0 is set. We do have lot of PCI pass-through devices.

Our Xen cfg file looks like this :-

# HVM specific
kernel = "hvmloader"
builder = "hvm"
device_model = "qemu-dm"

# Enable ACPI support
acpi = 1

# Enable serial console
serial = "pty"

# Enable VNC
vnc = 1
vnclisten = "0.0.0.0"

pci_msitranslate = 0

xen_platform_pci = 1

# Default behavior for following events
on_reboot = "destroy"


I'm use SLES SuSE 11 SP3.

Thanks,
/Saurabh

Right. That is expected.

Oh, that looks to be a bug then.

As you initial domain or your guests? If it is with SLES does the issue
show up if you use the latest version of Xen?

We have two VMs. One is a WindRiver based VM and the other one a SLES SuSE
11 SP2 VM.

SuSE 11 SP2 VM shutdown properly with xen_platform_pci=0 however WR one
does not and hence the question what config or driver do I need to enable
in WR HVM guest such that it accepts 'xl/xm trigger <vm> power'?

Lets step back a minute. What is the version of Xen you are running.

Oh, please don't top-post and please do use the latest version of Xen.

As I mentioned earlier - you might be hitting a bug in 'xl'. Hence
please use the latest version so that we can vet whether indeed this
is a bug when doing 'xl trigger'.

Re: xm/xl shutdown does not work with HVM guest

[Saurabh Mishra]

[-- Attachment #1.1: Type: text/plain, Size: 3588 bytes --]

Well -- We are using SuSE and don't want to build Xen ourself and SuSE's 11
SP3 pack has  Xen 4.2.2.

But what about 'xm trigger <vm> power'. That too didn't work with
xen_platform_pci=0. So I don't think it's a xl(1) bug.

Thanks,

Support for ACPI power events.

Hi Ian --

So enabling 'CONFIG_APM=y' in WR kernel for HVM guest should be enough? Let
me try that out.

Hi --

I tried enabling CONFIG_APM but it still didn't work. Let me know if you
guys happen to know what all needs to be enabled in guest HVM for ACPI
events to work (xm trigger <vm> power). Since SuSE HVM VM works with 'xm
trigger <vm> power', I'm suspecting we have not enabled something in our WR
distro.

What is 'WR'? Anyhow, you might also need ACPI. Do you get any ACPI
events at all in your guest?

Aka, does /proc/interrupts for acpi show an increasing number as you
do 'xl trigger poweroff' ?

WR is WindRiver distribution. I don't see any interrupt count going up for
acpi.

I don't see any ACPI events in the HVM guest either.

APM != ACPI. They are totally different things.

I'm afraid I don't know specifically what needs to be done in a distro
to support ACPI but it is the same thing as makes a physical system shut
down when you press the power button on the case. At a minumum there is
probably some package which needs to be installed, but I can't advise
more specifically for a WR system.

If I were you I'd be asking WR about their ACPI support.

With xl in the absence of PV drivers you can use "xl shutdown -F" to
fallback to an ACPI power event to shut things down, assuming the guest
is configured to respond to that.

Although if xl trigger power isn't working it sounds like this might not
work either.

Remember that this could also be a guest side bug, since it has to be
configured to respond to the event. I'd have thought that most modern
Linux distros and versions of Windows would do *something* by default
(either shutdown, reboot or in the case of Windows perhaps hibernate).

I wouldn't have expected xen_platform_pci to make any difference to the
functionality of this option, but it's not clear if that is implied by
the above.

Ian.
