http://bugzilla.novell.com/show_bug.cgi?id=626654 http://bugzilla.novell.com/show_bug.cgi?id=626654#c0 Summary: kernel has some unclear problems with hypervisor Classification: openSUSE Product: openSUSE 11.3 Version: Final Platform: x86-64 OS/Version: Other Status: NEW Severity: Major Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: nettezzaumanaa@gmail.com QAContact: qa@suse.de Found By: --- Blocker: --- Created an attachment (id=379230) --> (http://bugzilla.novell.com/attachment.cgi?id=379230) all /var/tmp/logs .. User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.10) Gecko/20100506 SUSE/3.5.10-0.1 Firefox/3.5.10 hi there, i've found very severe problem with kernel while using hypervisor (kvm for example) .. i experienced weird acting like big performance fluctuations are .. i also experienced in 11.3 that kernel has some troubles with netstack in kvm (qemu-kvm) .. currently i am unable to run properly under netstack while ran qemu-kvm .. i tested kvm package from repo oss and from here http://download.opensuse.org/repositories/Virtualization/openSUSE_11.3/ .. same behaviour occurs .. sorry for vague description but this issue seems very unclear to me .. i attached all my logs .. i need to mention several things left: 1) i don't use apparmor 2) i tested it with enabled ipv6 and also with disabled one 3) qemu in pure emulation mode runs fine 4) i didn't test it in 32 bit mode 5) i was so confused that i tested this also in debian and fedora .. it ran reasonable there .. feel free to request anything what you could consider as useful. regards, daniel Reproducible: Always Steps to Reproduce: 1. install kvm package (0.12.3-2.9 is current version), find some bootable iso . i tested it with solaris and knoppix .. solaris was normally installed 2. run virtual machine, i've been using following 100% working method for configuring ifaces: -net nic,model=e1000,vlan=1 -net tap,vlan=1,ifname=knic0,script=no check, that knic0 iface is created (via `ip a`) 3. set up in guest/host system interface (e1000g0 in solaris, eth0 in knoppix), assign address and put iface up
Linux: ip a a 192.168.100.100/24 dev eth0 ip l set eth0 up
Solaris: ifconfig e1000g0 plumb ifconfig e1000g0 192.168.100.100 netmask + broadcast +
kvm host system: ip a a 192.168.100.200/24 dev knic0 ip l set knic0 up
4) now ping and network *must* works .. but in case of kvm not i was been able to catch packets by using tcpdump from host system over knic0 but vice versa not .. nothing had gone through knic0 to guest from host .. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

What if you change that for virtio and give this a try in a knoppix guest? Also, reassigning to Bruce, the KVM maintainer. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Also, please try with also specifying a random mac address( add ,macaddr=xx:xx:xx:xx:xx:xx to -net nic parm), so as to avoid the potential of conflicting with an already recognized mac address in the guest. Also, perhaps try with rtl8139 model NIC to see if that works in your guests. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
