Dear libvirt expert:
Thanks for your replay, we are not restore from the same state file
twice, only one time. we have 40 process, each process handle it's own VM and
VM state file, and each process will do following things cycle:
While(1)
{
Virsh restore state file
do something in VM in 20s
virsh destroy vm
}
so we have sure now: There is currently no way to reduce these 40 xen
status files space.
When we do the above things, we got a xen crash on xen-4.7.0, so we try
to use the xen-4.8.2 and libvirt 2.5.0, and the crash problem is no longer
exist, but we got a new problem:
we add the <interface> in config fie of VM:
<interface type='bridge'>
<mac address='18:c5:8a:15:c1:39'/>
<source bridge='virbr0'/>
</interface>
When we use 'virsh create virsh_0.xml', we can't create the vm, and got
follow error:
2017-11-28 12:36:56.329+0000: 17489: error :
libxlDomainStart:1280 : internal error: libxenlight failed to create new domain
'aap_0'
error: Failed to create domain from virsh_0.xml
error: internal error: libxenlight failed to create new
domain 'aap_0'
and in the /var/log/libvirt/libxl/libxl-driver.log there have a log:
2017-11-28 20:36:53 CST libxl: error:
libxl_exec.c:118:libxl_report_child_exitstatus: /etc/xen/scripts/vif-bridge
online [17580] exited with error status 127
You need to determine why Xen's vif-bridge script failed. syslog should contain
info about that.
