Output of "strace qemu-kvm -localtime -m 512 -std-vga raw.img"
Yesterday, I've upgraded kvm to kvm-70. Could you please upgrade and see if this problem got fixed by any of upstream commit? By looking at the commit list, I very honestly don't think so. But let us try to focus on the topmost thing here ;-) In case the problem persists, can you provide us with some more info, like dmesg messages, if any suspicious, and host information? Nope. Fails with the same strace. Here are the last few lines: read(6, "\1\0001\0\5\0\0\0\22\0\320\10\0\0\0\0\10\0\0\0\0\0\0\0\20o\320\10\0\0\0\0"..., 4096) = 52 read(6, 0x9ad3ffc, 4096) = -1 EAGAIN (Resource temporarily unavailable) select(7, [6], [6], NULL, NULL) = 1 (out [6]) writev(6, [{"\20\1\4\0\7\0\0\0LOCALES\0", 16}], 1) = 16 select(7, [6], [], NULL, NULL) = 1 (in [6]) read(6, "\1\0002\0\0\0\0\0k\1\0\0\0\0\0\0\20\0\0\0\0\0\0\0\20o\320\10\0\0\0\0", 4096) = 32 read(6, 0x9ad3ffc, 4096) = -1 EAGAIN (Resource temporarily unavailable) select(7, [6], [6], NULL, NULL) = 1 (out [6]) writev(6, [{"\30\1\6\0\4\0\0\4q\1\0\0k\1\0\0k\1\0\0\0\0\0\0", 24}], 1) = 24 select(7, [6], [], NULL, NULL This worked as late as last Thursday, so I'm guessing its due to an update since then. I'll try to strace qemu-kvm running as root and see if I can see anything in the "diff". There is nothing in /var/log/messages that I can see. Running on Thinkpad X60, latest rawhide, kernel-2.6.26-0.74.rc6.git4.fc10.i686 Mysterious..... after today's rawhide updates, and some fiddling with nscd, this started working. Let me probe on this for a day or so. If it no longer fails, I'll close this BZ. So it's probably related to some other issue, on another package. Last kvm update (excluding yesterday one), was done much earlier than last tuesday. I can no longer reproduce this; must be ghosts ;) Closing as NOTABUG |
