Title:
  [KVM][CLX] CPUID_7_0_EDX_ARCH_CAPABILITIES is not enabled in VM.

Status in intel:
  New
Status in linux package in Ubuntu:
  Confirmed
Status in qemu package in Ubuntu:
  Triaged

Bug description:
  This is a bug.

  Test Environment:

  Repro Steps:

  1. Boot up guest using: -cpu Cascadelake-Server

  [root@clx-2s2 yexin]# qemu-system-x86_64 -accel kvm -drive
  if=virtio,id=hd,file=/home/x/x,format=qcow2  -m 4096 -smp 4 -cpu
  Cascadelake-Server -serial stdio

  char device redirected to /dev/pts/3 (label serial0)

  qemu-system-x86_64: warning: host doesn't support requested feature:
  CPUID.07H:ECX [bit 4]

  qemu-system-x86_64: warning: host doesn't support requested feature:
  CPUID.07H:ECX [bit 4]

  qemu-system-x86_64: warning: host doesn't support requested feature:
  CPUID.07H:ECX [bit 4]

  qemu-system-x86_64: warning: host doesn't support requested feature:
  CPUID.07H:ECX [bit 4]

  2. To check CPU ID related to features[FEAT_7_0_EDX]
  :CPUID_7_0_EDX_ARCH_CAPABILITIES

  Expected Result: Both host and guest's CPUID.07H EDX bit 29 should be
  1.

  Actual Result:

  Host's cpuid: 0x00000007 0x00: eax=0x00000000 ebx=0xd39ffffb
  ecx=0x00000818 edx=0xbc000000  (EDX bit 29=1)

  Guest's cpuid : 0x00000007 0x00: eax=0x00000000 ebx=0xd19f0fb9
  ecx=0x00000818 edx=0x84000000 (EDX bit 29=0)
