2013-12-18s390x/ioinst: CHSC has to set a condition codeThomas Huth1-0/+1
I missed to set the CC in the CHSC instruction when I refactored the CC setting in the IO instructions with the following commit: 5d9bf1c07c1369ab3506fc82cc65a10f4415d867 s390/ioinst: Moved the CC setting to the IO instruction handlers This patch now restores the correct behaviour of CHSC by setting the condition code 0 at the end of the instruction.

But guest memory allocation failure isn't, and aborting when the user asks for more memory than we can provide is not nice. exit(1) instead, and do it in just one place, so the error message is consistent.

2013-08-30s390: wire up nmi command to raise a RESTART interrupt on S390Eugene (jno) Dvurechenski2-3/+16
There is the 'nmi' command that is used to trigger a guest dump via kdump feature on x86. s390 uses RESTART interrupt to trigger kdump. So, this patch provides a mean to use 'nmi' command on s390 to raise RESTART interrupt. The CPU to receive the RESTART interrupt is the "default" one. There is an infrastructure to select the "default" CPU using 'cpu' command. The 'info cpus' command can be used to see which one is the "default". In order to wire up the RESTART to 'nmi' command we had to: 1. implement the kvm_s390_cpu_restart function by exporting the existing code 2. implement s390_cpu_restart function as kvm-aware wrapper 3. modify the qmp_inject_nmi function to enable (for s390) the scan for "default" CPU and call s390_cpu_restart for it; 3. fix some messages.

Commit c643bed99 moved qemu_init_vcpu() calls to common CPUState code. This causes x86 cpu-add to fail with "KVM: setting VAPIC address failed". The reason for the failure is that CPUClass::kvm_fd is not yet initialized in the following call graph: ->x86_cpu_realizefn ->x86_cpu_apic_realize ->qdev_init ->device_set_realized ->device_reset (hotplugged == 1) ->apic_reset_common ->vapic_base_update ->kvm_apic_vapic_base_update This causes attempted KVM vCPU ioctls to fail. By contrast, in the non-hotplug case the APIC is reset much later, when the vCPU is already initialized.
