Re: Announcing qboot, a minimal x86 firmware for QEMU
2015-05-23 6:55 GMT+03:00 Kevin O'Connor ke...@koconnor.net: Out of curiosity, I ran some additional timing tests. With SeaBIOS fully stripped down (via Kconfig), it takes ~20ms to get to the boot phase on my old AMD system. Of that 20ms, ~7ms is to enable shadow ram, 2ms is to calibrate the cpu timestamp counter, 4ms is for pci init, and ~6ms is to make the shadow ram area read-only. The time in the remaining parts of the SeaBIOS code is so small that it's hard to measure. Can you share config for seabios? As i understand i can safety to remove keybord, ps2, usb, ata/ahci and leave only virtio (in case of using qemu to boo linux/freebsd/windows systems) ? -- Vasiliy Tolstov, e-mail: v.tols...@selfip.ru -- To unsubscribe from this list: send the line unsubscribe kvm in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I just tried using nested vmx for the first time since upgrading my system from F19 (3.12.?? at the time) to F20, and I cannot start any L2 guests. The L2 guest appears to hang almost immediately after starting, consuming 100% of one of the L1 guest's VCPUs. If I reboot with kernel-3.12.10-300.fc20.x86_64, the problem does not occur. Any known workaround? (Other than using 3.12.10?) There is a fix on the way to the 3.13 kernel. You can open a Fedora bug and ask them to include http://article.gmane.org/gmane.linux.kernel.stable/82043/raw in the kernel. Thanks for fixing this. It affects a lot of libguestfs users too.

2014-03-14 15:58 GMT+04:00 Richard W.M. Jones rjo...@redhat.com: It could be there is another, less frequent, bug in nested KVM. I'm assuming this is on Intel hardware? From the libguestfs point of view what you can do is to force TCG: export LIBGUESTFS_BACKEND_SETTINGS=force_tcg Unfortunately this only has an effect in libguestfs = 1.25.24. We're going to have the new version in Fedora 20 real soon -- probably before the end of this month. Or you can compile the Rawhide version on F20. Thanks for answer. I'm not using libguestfs.
