Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed
Status in QEMU:
Fix Released
Bug description:
Hello,
I see the following when try to run qemu from master as the following:
# ./x86_64-softmmu/qemu-system-x86_64 --version
QEMU emulator version 2.8.50 (v2.8.0-1006-g4e9f524)

qemu-system-x86_64: /home/matwey/lab/qemu/target/i386/kvm.c:1849:
kvm_put_msrs: Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed.
First broken commit has been bisected:
commit 48e1a45c3166d659f781171a47dabf4a187ed7a5
Author: Paolo Bonzini <pbonzini@redhat.com>
Date: Wed Mar 30 22:55:29 2016 +0200
target-i386: assert that KVM_GET/SET_MSRS can set all requested MSRs
This would have caught the bug in the previous patch.
