[Qemu-devel] [PATCH v2] target-i386: present virtual L3 cache info for vcpus

From: "Longpeng(Mike)" Some software algorithms are based on the hardware's cache info, for example, for x86 linux kernel, when cpu1 want to wakeup a task on cpu2, cpu1 will trigger a resched IPI and told cpu2 to do the wakeup if they don't share low level cache. Oppositely, cpu1 will access cpu2

[Qemu-devel] [Bug 1414466] Re: -net user, hostfwd=... is not working(qemu-system-aarch64)

I think this is not a bug, but you are using the command line parameters in a wrong way. When you use "-net user,hostfwd=tcp:127.0.0.1:1122-:22" you are creating a *new*, second host network device which is not connected to the guest NIC device that you specified. Please try to avoid mixing "-net"
