In the past month or two, I have consistently encountered an odd problem with Wheezy on an AMD 8350 CPU. I never had this problem with my quad Phenom-II.
The problem ----------- When I install recent builds of 32- and 64-bit Smoothwall Express 3.1 in a KVM on 64-bit Wheezy, everything seems to work well. Except for one thing. Smoothwall has a program that collects interface byte & packet peg counts from iptACCOUNT and possibly directly from netfilter every two seconds. The bandwidthbars and trafficmonitor UI pages are supposed to display the current bit rate. This problem makes the displayed rates climb very slowly and fall glacially. Also, the interfaces are weird. I've seen it display 170Mb/s throughput through a 100Mb/s NIC, and at least 1.9Gb/s through a physical gigE LAN. And no transmit/receive errors appear on any NIC's ifconfig output. It happens on kernel 3.2, 3.12 and 3.14. It happens with Wheezy's kvm() and with qemu 1.7.x built from scratch. It happens with emulated e1000 NICs and with virtio. Comparison ---------- The exact same ISO installed on iron with a dual-core Athlon works as expected. And it works OK in that other computer in a KVM on Squeeze. (In fact, I NFS-mounted my KVM stuff from the desktop to this test system, so the method is identical.) I haven't yet tried removing the HDs from my vishera desktop and installing the ISO directly. Or booting the Squeeze HD on the vishera. Or trying a different distro. Or even installing Wheezy from scratch on a spare drive. Queries ------- Has anyone else seen behavior like this in KVM sessions on Wheezy? Or is it just my recent bad luck with computers? Where/how should I dig to narrow down the scope of the problem? Is it possible to install older kernels, qemu/kvm and other pkgs as needed to try to find a combination that works?
