Hi, When I resume a VM from suspend that is based on iscsi or fcp, there's always an exception: ----- 2019-04-17 19:33:58,835+0800 ERROR (vm/baaabf11) [virt.vm] (vmId='baaabf11-172d-4fac-9862-86ff05feb085') The vm start process failed (vm:937) 378 Traceback (most recent call last): 379 File "/usr/lib/python2.7/site-packages/vdsm/virt/vm.py", line 866, in _startUnderlyingVm 380 self._run() 381 File "/usr/lib/python2.7/site-packages/vdsm/virt/vm.py", line 2819, in _run 382 self._connection.restore(fname) 383 File "/usr/lib/python2.7/site-packages/vdsm/common/libvirtconnection.py", line 131, in wrapper 384 ret = f(*args, **kwargs) 385 File "/usr/lib/python2.7/site-packages/vdsm/common/function.py", line 94, in wrapper 386 return func(inst, *args, **kwargs) 387 File "/usr/lib64/python2.7/site-packages/libvirt.py", line 4513, in restore 388 if ret == -1: raise libvirtError ('virDomainRestore() failed', conn=self) 389 libvirtError: internal error: Child process (gzip -dc) unexpected exit status 2: 390 gzip: stdin: decompression OK, trailing garbage ignored 391 392 2019-04-17 19:33:58,835+0800 INFO (vm/baaabf11) [virt.vm] (vmId='baaabf11-172d-4fac-9862-86ff05feb085') Changed state to Down: internal error: Child process (gzip -dc) unexpected exit status 2: 393 gzip: stdin: decompression OK, trailing garbage ignored 394 (code=1) (vm:1675) ---------- After i read the Bug 1503468 (https://bugzilla.redhat.com/show_bug.cgi?id=1503468#c40), I know the reason why that happened. But how should I avoid this exception? The only method i know and tested is to change gzip to lzop in /etc/libvirt/qemu.conf. But this is not the way to solve the problem. -- 王猛 软件研发 手机：13021702660 地址：济南市高新区银荷大厦B座10层 250101 邮箱: wang_meng(a)massclouds.com 网址: www.massclouds.com 山东乾云启创信息科技有限公司
