[Resending as the last copy seems to have been lost in the ether -- it certainly isn't in the GMANE archive] Well, behavior with the patch applied is certainly different. The large download I'm running still times out; however, it is now able to resume without needing to bring the interface down

[Qemu-devel] Network connections stalling (due to lost interrupts/ticks?)

2007-08-02 Thread Charles Duffy
I'm trying to use qemu to test an install process which involves quite a bit of downloading. Everything starts up fine (using either ne2k_pci or rtl8139 hardware), but the multi-GB download typically stalls out about 100-400MB in. Is there anything I can do to prevent this? There's a warning o

[Qemu-devel] etherboot support in x86_64 mode?

2007-08-02 Thread Charles Duffy
I notice that the "-boot n" etherboot support doesn't appear to work when emulating x86_64 hardware (invocation as qemu-system-x86_64). Is this intentional? A known issue?
