https://bugzilla.kernel.org/show_bug.cgi?id=206447 Bug ID: 206447 Summary: __skb_get_hash_symmetric makes tun queue not balance Product: Virtualization Version: unspecified Kernel Version: 3.10.0-862.14 and later Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: kvm Assignee: virtualization_kvm@xxxxxxxxxxxxxxxxxxxx Reporter: glovejmm@xxxxxxx Regression: No We use tun ko to creaste a vm with ovs, We found thst tun_select_queue changed the hash method from skb_get_hash to __skb_get_hash_symmetric, in higher kernel version. What refuse us is it is quite balance in tun queue select in old version, while it is often focus on 1-2 queues in new version with above change. When we rollback the hash methd to skb_get_hash with kernel recompile , balance recover normal again . Is there any config or patch relation with this hash not balance problem? here is the change patch https://patchwork.ozlabs.org/patch/643209 -- You are receiving this mail because: You are watching the assignee of the bug.
