Reply-To: charles@dyfis.net, qemu-devel@nongnu.org List-Id: qemu-devel.nongnu.org List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: qemu-devel@nongnu.org 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 on startup that the system can't set a 1024Hz timer, which persists even after I set /proc/sys/dev/rtc/max-user-freq to 1024, and I occasionally get warnings at runtime ("Your time source seems to be instable or some driver is hogging interrupts").
