Considering you are using libvirt/KVM, libvirt asks qemu to get information about block stats. You can begin by executing the command from libvirt and compare the result. virsh domstats <domain> If results are equivalent we can probably avoid that the problem comes from Nova. Also you could connect yourself to the VM or using libguestfs to execute some commands and get information about errors. s. > jichen@cloudcontroller:/opt/stack/nova/nova$ nova diagnostics jieph1 > +---------------------------+----------------------+ > | Property | Value | > +---------------------------+----------------------+ > | cpu0_time | 10710000000 | > | hdd_errors | 18446744073709551615 | > ....................... > | tapf1ce9c02-01_tx_packets | 24 | > | vda_errors | 18446744073709551615 | > | vda_read | 2848768 | > | vda_read_req | 453 | > | vda_write | 348160 | > | vda_write_req | 105 | > | vdb_errors | 18446744073709551615 | > | vdb_read | 829440 | > | vdb_read_req | 30 | > | vdb_write | 4096 | > > Best Regards! > > Kevin (Chen) Ji 纪 晨 > > Engineer, zVM Development, CSTL > Notes: Chen CH Ji/China/IBM@IBMCN Internet: jiche...@cn.ibm.com > Phone: +86-10-82454158 > Address: 3/F Ring Building, ZhongGuanCun Software Park, Haidian District, > Beijing 100193, PRC > _______________________________________________ > OpenStack-dev mailing list > OpenStack-dev@lists.openstack.org > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
