Hi,

Any hint on what is the problem? How can one debug similar issues?

Thx Marco
 
Seems you VM does not stop correctly - you need working ACPI inside the VM to make that work. What kind of OS do you run?

You can also use snapshot or suspend mode to avoid that problem at all.
 
running OS is Ubuntu 8.04.4 server

proxmox1:~# cat /etc/qemu-server/101.conf
ostype: l26
memory: 512
sockets: 1
name: VMapimix01
ide2: none,media=cdrom
bootdisk: scsi0
onboot: 0
cores: 1
ide0: vm_disks:vm-101-disk-1
vlan0: rtl8139=C2:E2:B5:3B:C8:BA

btw, snapshot mode worked (kvm is on LVM2), took just 7 minutes...

Thanks.

do you think i should activate acpi anyway?

anyway, just to make experience, looking for info, i searched for acpi inside the vm:
$ aptitude search acpi
p acpi - displays information on ACPI devices
p acpi-support - a collection of useful events for acpi
p acpid - Utilities for using ACPI power management
p acpidump - utilities to dump system's ACPI tables to
p acpitail - Show ACPI information in a tail-like style
p acpitool - a small, convenient command-line ACPI clie

so no package installed...
will acpid package be sufficient in your opinion? is there any other useful package/setting i should consider?
grub loads the kernel with standard options, and there's no mention of acpi options anywhere...
i think that the os installer should detect if the bios (in this case the kvm bios) supports acpi and install support for it.
i did not check the "disable acpi" flag in vm config, so... is something gone wrong during install, or acpi support is totally in charge of the server user to install?

Mnay thanks, again. Marco
 
ok, i recently started with linux os so i have much to learn...
so the 'stop' button on the web manager does something different than acpi-asking th evm to stop,like killing host processes, or so, i think?

Many thanks, Dietmar

Click to expand...

Yes, stop 'kills' the VM process.
