How is the CPU doing? Could this be the issue? Bug 949547 - qemu-kvm process consumes 8% cpu even when windows guest is idle inside and 70% when guest uses 10% cpu inside Is a Linux guest any better? Deferring to RHEL6.6, since supporting 24 USB disks inside a Win guest is probably not high priority. Closing. Unlikely to be fixed in RHEL6. Please test with RHEL7, and file a new BZ (In reply to Ronen Hod from comment #4) > Closing. > Unlikely to be fixed in RHEL6. > Please test with RHEL7, and file a new BZ Seems we missed this needinfo before. Can we have a test and update the testing result in the bz?

Created attachment 654707 [details] error device cannot start Description of problem: ------------------------ Attach 24 usb-storage device to windows guest, sometimes after reboot one disk can not be used with error "device cannot start". Version-Release number of selected component (if applicable): -------------------------------------------------------------- qemu-kvm-rhev-0.12.1.2-2.331.el6.x86_64 guest: win7-64 How reproducible: ------------------ 50% Steps to Reproduce: -------------------- 1. boot guest with 24 usb storage 2. reboot guest repeatedly, check device manager, sometimes one disk with error "device cannot start", see screenshot in attachment. Additional info: ----------------- I test 6 usb-storage on one echi controller, won't hit this problem, so the number of usb-storage does have matter.
