Re: [kvm-devel] kvm-15 on top of 2.6.20 - unresolved symbols

Finally I got some time and played with this some more. The unresolved symbols are caused by the fact that the kvm module fails to load: FATAL: Error inserting kvm (/lib/modules/2.6.20/extra/kvm.ko): Device or resource busy I narrowed it down the following: r = register_filesystem(&kvm_fs_type);

[kvm-devel] [RFC][KVM] Adding a signal mask to KVM_RUN

2007-03-01 Thread Avi Kivity
I'd like to add a signal mask to kvm, so that when the guest executes, the signal mask is temporarily set to some user specified value. This allows signals to be used as a way to interrupt the guest, but without requiring signal delivery to the userspace handler (which is what makes signals ex
