kvm-36 is repeatedly timing out partway through a long network transfor and failing to resume. Both host and guest are 64-bit. This has happened with a number of prior releases as well; it does not appear to be a recently-introduced issue.
My command line looks like the following: $ qemu-system-x86_64 -kernel kernel-x86_64-2.6.20-gentoo-r8 -initrd initramfs.igz -hda hda -hdb hdb -append "panic=30 console=ttyS0 action=install" -nographic -net nic -net 'tap,ifname=tap0,script=./tap0-start' /dev/kvm is quite certainly being used, as KVM immediately segfaults on startup without it (or in the presence of the -no-kvm option). dmesg on the host shows a great number of "rtc: lost some interrupts at 1024Hz" messages. The end of a typical session looks much like the following: ==== 79000K .......... .......... .......... .......... .......... 4% 5.43M 4:33 79050K .......... .......... .......... .......... .......... 4% 6.10M 4:03 79100K .......... .......... .......... .......... .......... 4% 8.14M 3:02 79150K ...... 4% 5.96M 4:09 02:45:23 (2.06 MB/s) - Read error at byte 81055847/1639127012 (Connection timed out).

I am more reliably able to reproduce this issue using -net tap than -net user. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
