xen 3.0.2 dom0 (kernel 2.6.16-xen) always crashes, or rather freezes, whenever I copy more than 40GB of data. i checked syslog and there is no indication at all why it crashes. this happens whether the OS is FC5 or mandriva 2006, and is also independent of hardware, although we have mostly dell poweredge (1750, 2850, etc.) i am wondering if there some workaround. thanks!

[Xen-users] Re: xen dom0 crashes while copying a lot of files
for this , I suggest u to install the bianary version of xen , not to compile and install by yourselfit.That would be more stable.

[Xen-users] RE: xen dom0 crashes while copying a lot of files
i have been using the binary installation from xen source (3.0.2). although i did not do a thorough testing, if i shut down xend and xendomains services, and then does the copy, the kernel itself did not crash. then i can turn on these services again. probably this could be a workaround but i am not sure.

[Xen-users] RE: xen dom0 crashes while copying a lot of files - usb support to blame
To answer my own question, I finally figured it out that the usb was the culprit. Passing nousb to the domU kernel solves the problem beautifully. I accidentally bumped into the solution when I installed Fedora Core as a VMWare guest, and xenified the FC guest without usb. The xen guest vms within the FC vmware vm does not crash with heavy I/O. I confirmed that usb was the problem by finding this document by dell engineers. Had I found it earlier, I would not have wasted so much time on this and other things that dell engineers already figured out. Oh, well, this sort of things happens. http://www.dell.com/downloads/global/power/ps2q06-20050322-Schmidt-OE.pdf#search=%22xen%20dell%20poweredge%202850%22 It works for me and hope it will also work for you. It might be useful for others as well so I am copying the mailing list as well.
