I test migration from rhel7.1->rhel7.2 with sound device, also hit this problem.
When the migration failed, I check "info qtree"
For qemu-kvm-rhev-2.1.2-23.el7 on src host:
(qemu) info qtree
bus: pci.0
type PCI
dev: intel-hda, id "sound0"
debug = 0 (0x0)
msi = 1 (0x1)
addr = 04.0
romfile = ""
rombar = 1 (0x1)
multifunction = false
command_serr_enable = true
class Audio controller, addr 00:04.0, pci id 8086:2668 (sub 1af4:1100)
bar 0: mem at 0xfebf0000 [0xfebf3fff]
bus: sound0.0
type HDA
dev: hda-duplex, id "sound0-codec0"
debug = 0 (0x0)
mixer = true
cad = 0 (0x0)
For qemu-kvm-rhev-2.2.0-8.el7 on dst host:
(qemu) info qtree
bus: pci.0
type PCI
dev: intel-hda, id "sound0"
debug = 0 (0x0)
msi = 1 (0x1)
old_msi_addr = false
addr = 04.0
romfile = ""
rombar = 1 (0x1)
multifunction = false
command_serr_enable = true
class Audio controller, addr 00:04.0, pci id 8086:2668 (sub 1af4:1100)
bar 0: mem at 0xfebf0000 [0xfebf3fff]
bus: sound0.0
type HDA
dev: hda-duplex, id "sound0-codec0"
debug = 0 (0x0)
mixer = true
cad = 0 (0x0)
Add "old_msi_addr=true" to the dst commandline as following, the migration can be finished normally:
-device intel-hda,id=sound0,bus=pci.0,addr=0x4, old_msi_addr=true
Ah thank you; yes that should be easy to fix then; we just need to tie that to a new machine type. qemu-kvm-rhev-2.3.0-1.el7 should fix this using the new machine type from bz 1210050. Fixed by rebase... I do migration RHEL7.1 -> RHEL7.2 with the device ich9-intel-hda, also hit this bug.

After migration from RHEL7.1 to RHEL7.2, the migration can be finished normally. Inside guest, can play audio normally.
