Hi,
Has anyone met the same problem that virsh hangs when there are some backup jobs running on the kvm host? I use dirty bitmap supported by qemu to do backups every 6 minitues. About a few hours later, I ran 'virsh list', It hung. Then I stopped the backup
jobs ，nothing was getting better. I had checked the libvirt logs ，but found nothing useful .
Maybe the high I/O caused the problem? or there are connection number limits when using virsh, because I use virsh to check the backup jobs are still running every 10 seconds?
My os version is ' Ubuntu 12.04 LTS Release: 12.04 Codename: precise,Linux version 4.1.0-generic (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!
