L2 SMP guest (without nested guest support (with nesting I haven't see the issue so far)) can have I/O related issues when the L2 guest has more than 1 vcpu, and the L1 guest is on a low latency drive 'unsafe' cache enabled. Now the Opnestack gate using 1 VCPU with the L2 F20, no issue seen since that. I am going to try to reproduce the issue on full Fedora system. (normally I have enabled nested virt on F20 L0). The issue can be seen on F20 L1+L2, with el6 L0. > > -- > Matthew Miller > <mattdm@xxxxxxxxxxxxxxxxx> > Fedora Project Leader > _______________________________________________ infrastructure mailing list infrastructure@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/infrastructure
