Title:
save guest running time is more than 450s with AVX running.
Status in QEMU:
New
Bug description:
Environment:
------------
Host OS (ia32/ia32e/IA64):ia32e
Guest OS (ia32/ia32e/IA64):ia32e
Guest OS Type (Linux/Windows):linux
kvm.git Commit:d6d63b51fe3bfea0cf596993afa480b0b3b02c32
qemu.git Commit:8f84271da83c0e9f92aa7c1c2d0d3875bf0a5cb8
Host Kernel Version:3.13.0-rc1
Hardware:Romley_EP, Ivytown_EP
Bug detailed description:
--------------------------
when guest running avx , then do save /restore, save guest running time is
too lomg
Note:
1.when save guest (migrate "exec:dd of=test.img")sometimes , the file of
test.img is 29G, running time of save guest is about 900s
2. this should be a qemu bug:
kvm + qemu = result
d6d63b51 + 8f84271d = bad
d6d63b51 + b5d54bd4 = good
Reproduce steps:
----------------
1.qemu-system-x86_64 -enable-kvm -m 1024 -smp 6 -net
nic,macaddr=00:12:34:43:14:78 -net tap,script=/etc/kvm/qemu-ifup rhel6u4.qcow
2. scp /usr/tet/XVS/tsets/control_panel/tools/bin/avx.tar.gz $guest_IP:/root
3. tar -zxf avx.tar.gz
4. cd /avx
5. sh chk_avx.sh &>/dev/null &
6. ctrl-alt-2
7. migrate "exec:dd of=test.img"
Current result:
----------------
running time of save guest is more than 450s
Expected result:
----------------
running time of save guest is less than 450s
Basic root-causing log:
