qemu: check if block I/O limits fit into long long
We can only pass values up to LLONG_MAX through JSON
and QEMU checks if the int64_t number is not negative
at startup since 1.5.0.

git describe: v1.0.6-120-gd3c8788
Reproduce the bug with same version #rpm -qa libvirt qemu-kvm kernel qemu-kvm-1.5.0-2.el7.x86_64 libvirt-1.0.6-1.el7.x86_64 kernel-3.9.0-0.55.el7.x86_64 verify this bug with libvirt-1.1.0-1.el7.x86_64.
Steps:
1. prepare one running guest.
2. Set iotune total_bytes_sec
# virsh blkdeviotune kvm-rhel6.3-x86_64-qcow2-virtio vda --total-bytes-sec 12212221112000930000
error: Unable to change block I/O throttle
error: numerical overflow: block I/O throttle limit value must be less than 9223372036854775807
3. Set iotune total_bytes_sec with option --config
#virsh blkdeviotune kvm-rhel6.3-x86_64-qcow2-virtio hda --total-bytes-sec 12212221112000930000 --config
error: Unable to change block I/O throttle
error: numerical overflow: block I/O throttle limit value must be less than 9223372036854775807
4. check in the inactive dumpxml
# virsh dumpxml kvm-rhel6.3-x86_64-qcow2-virtio --inactive |grep -A 5 disk
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2' cache='none'/>
<source file='/var/lib/libvirt/images/kvm-rhel6.3-x86_64-qcow2.img'/>
<target dev='hda' bus='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/>
</disk>

The error is clear, so verify this bug.

Description of problem It should report error while the bps or iops values are not supported by guest. Version-Release number of selected component (if applicable): libvirt-1.0.6-1.el7.x86_64 kernel-3.9.0-0.55.el7.x86_64 qemu-kvm-1.5.0-2.el7.x86_64 How reproducible: 100% Steps 1. prepare one running guest. 2. Set iotune total_bytes_sec # virsh blkdeviotune b hda --total-bytes-sec 12212221112000930000 error: Unable to change block I/O throttle error: internal error Unexpected error 3. Set iotune total_bytes_sec with option --config #virsh blkdeviotune b hda --total-bytes-sec 12212221112000930000 --config 4. check in the inactive dumpxml # virsh dumpxml b --inactive |grep -A 5 disk <disk type='file' device='disk'> <driver name='qemu' type='qcow2' cache='none'/> <source file='/var/lib/libvirt/images/kvm-rhel6.4-x86_64-qcow2.img'/> <target dev='hda' bus='ide'/> <iotune> <total_bytes_sec>12212221112000930000</total_bytes_sec> ...... 5. destroy this domain and start it again. # virsh destroy b Domain b destroyed # virsh start b error: Failed to start domain b error: internal error process exited while connecting to monitor: char device redirected to /dev/pts/1 (label charserial0) qemu-kvm: -drive file=/var/lib/libvirt/images/kvm-rhel6.4-x86_64-qcow2.img,if=none,id=drive-ide0-0-0,format=qcow2,cache=none,bps=12212221112000930000: bps and iops values must be 0 or greater Actual results: as steps Expected results: It should report error in step3 if the bos or iops valuses are not supportted by guest. The error message should be same as the one in step 2.
