/proc/cpuinfo is emulated by qemu by intercepting any system call
which tries to open that file.  Under qemu:

  $ cat /proc/sysinfo
  /bin/cat: /proc/sysinfo: No such file or directory
  $ cat /proc/cpuinfo 
  Processor			   : AArch64 Processor rev 0 (aarch64)
  processor			   : 0
  BogoMIPS			   : 200.00
  
  Features			   : fp asimd 
  CPU implementer			   : 0x41
  CPU architecture: AArch64
  CPU variant	  : 0x0
  CPU part	  : 0xd00
  CPU revision	  : 0
  
  Hardware	  : V2P-AARCH64

However my understanding of this test is that it doesn't use
/proc/cpuinfo from the system, but uses the test data from
tests/sysinfodata/aarch64cpuinfo.data, and since it is using fixed
test data, the test output should be identical.

Therefore this appears to be a genuine libvirt bug.  I will post a
patch in a few minutes.

This one fails because:

  getifaddrs: Address family not supported by protocol

getifaddrs first calls socket(PF_NETLINK, SOCK_RAW, 0) [see netlink(7)].

This seems firmly in the category of qemu emulation failure, so I
think we should ignore it.
