After the mail below I rebooted the whole system (e.g. the host). Since then the guest runs fine. But this problem happened before so I'm not confident all is fine now. On Sun, Jul 21, 2013 at 03:38:56AM +0200, folkert wrote: More details: pinging from within the guest gives ping: sendmsg: No

[PATCH] ARM(64): KVM: add signed type cast for comparation

2013-07-21 Thread Chen Gang
'len' is 'unsigned long' which is never less than zero. So need a related type cast for comparation. The related warning (when building ARM64 with allmodconfig): arch/arm64/kvm/../../../arch/arm/kvm/mmio.c:82:2: warning: comparison of unsigned expression 0 is always false [-Wtype-limits]

[PATCH] ARM64: include: asm: use 'int' instead of 'u32' for variable 'target' in kvm_host.h.

2013-07-21 Thread Chen Gang
'target' will be set to '-1' in kvm_arch_vcpu_init(), and it need check 'target' whether less than zero or not in kvm_vcpu_initialized(). So need define target as 'int' instead of 'u32', just like ARM has done. The related warning: arch/arm64/kvm/../../../arch/arm/kvm/arm.c:497:2: warning:
