guest info: Windows 2003 64bit there's a work around (not knowing is it always work, I tried it 3 times and all works ) : hot plug a disk to guest will resolve this problem: 1) I hot-plugged a disk to guest,after guest search drivers,open "disk management",the hot-plugged disk can be initialized and formatted easily. 2)there are 2 disks I try to format it multiple time but didn't success,after hot-plugged a disk,they can be formatted easily as well. hot-plug cmd: (qemu) pci_add pci_addr=auto storage file=/hot1.qcow2,if=virtio I've been trying to reproduce this problem, but so far I've been unable to reproduce this issue. Hence, I have several questions to you: - is the above command line correct? There is no CD-ROM, mentioned in the command line, but it appears on the picture https://bugzilla.redhat.com/attachment.cgi?id=510204. How did you attached it? - is the problem reproducible with two disks of the same type (two virtio disks or two IDE)? Best regards, Vadim.

I have tested virtio RAID-5 configuration several times in the past, but didn't any problem. Best regards, Vadim. > > > Kind regards, > Xiaoqing. Hi Xiaoqing, I tried to reproduce this problem a huge amount of times during the last several days. I have tried platforms and different storage subsystem configuration. But I cannot reproduce this problem on my system. From my own experience I can say that we have seen similar problems several time. None of them were related to virtio block or IDE drive, but rather were a NFS or a host storage subsystem's problems. There is nothing related to virtio-win drivers we can fix. I'm going to close it as NOTABUG. But please feel free to reopen it in 6.3 if you don't agree with me. Best regards, Vadim. |
Created attachment 510204 [details] time-out error Description of problem: guest can not format hard drive Version-Release number of selected component (if applicable): kvm-83-238.el5 kvm-qemu-img-83-238.el5 How reproducible: mostly Steps to Reproduce: 1.create images : qemu-img create -f qcow2 storage1.qcow2 1G qemu-img create -f qcow2 storage2.qcow2 1G 2.start guest with above extra images attached (one ide, one virtio) : qemu-kvm .... -drive file=guest_os.qcow2,if=virtio,index=0.. -drive file=storage.qcow2,if=virtio,index=1.. -drive file=storage2.qcow2,if=ide,index=2.. 3.open "disk management" and format disks, Actual results: wait a long time and guest return time-out error(please see snapshot). Expected results: guest format disks without any problem Additional info: 1) after error occured,delete disk partition and retry format,sometimes disks can be formatted. 2) virtio seems easier to be formatted when retry.
