[Qemu-devel] question about qemu-monitor-event result redirecting to a file

[Zhan Adlun]

Dear Sir:
      Sorry to bother you. I use dirty bitmap to do backup in KVM. I could get 
output from the terminal when I use the command ' virsh qemu-monitor-event 
DOMAIN --timestamp --loop', but when using ' virsh qemu-monitor-event DOMAIN 
--timestamp --loop > /file ' to redirect the output to a file, I got nothing 
both from the terminal and the file. My os version is 'Distributor ID: Ubuntu   
Description: Ubuntu 12.04 LTS   Release: 12.04   Codename: precise,Linux 
version 4.1.0-generic (address@hidden) (gcc version 4.6.3 (Ubuntu/Linaro 
4.6.3-1ubuntu5) ) #1 SMP Wed Nov 9 02:04:23 CST 2016'. KVM version is 'QEMU 
emulator version 2.7.1(Debian 1:2.7+dfsg-3)'. Hoping for you reply. Thanks!
