Re: FreeBSD PVHVM call for testing
Hi, I've just successfully run FreeBSD 9.1 based guest with 'pvhvm_v8' based kernel under Xen 4.2.2. So I couldn't confirm any issue with the kernel both on Xen 3.4.4 and 4.2.2. Nice Job.

Re: virtio-net vs qemu 1.5.0
Hello, I filed a bug: http://www.freebsd.org/cgi/query-pr.cgi?pr=178955 Julian On 05/23/2013 02:00 PM, Julian Stecklina wrote: Hello, I just compiled qemu 1.5.0 and noticed that virtio network (on CURRENT as of today) seems to have problems updating the MAC filter table: vtnet0: error setting host MAC filter table As far as I understand, if_vtnet.c does the following in vtnet_rx_filter_mac. It appends two full struct vtnet_mac_tables (one for unicast and one for multicast) to the request. Each consists of the number of actual entries in the table and space for 128 (mostly unused) entries in total. The qemu code parses this differently. It first reads the number of elements in the first table and then skips over so many MAC addresses and then expects the header to the second table (which in our case points to zero'd memory). Then it skips those 0 MAC entries as well and expects that it has consumed the whole request and returns an error, because there is still data left. The relevant code is in qemu/hw/net/virtio-net.c in virtio_net_handle_rx_mode. Assuming the qemu code is correct (of which I am not sure) the correct solution would be to enqueue only so many MACs in the original requests as are actually used. The following (a bit dirty) patch fixes this for me: diff --git a/sys/dev/virtio/network/if_vtnet.c b/sys/dev/virtio/network/if_vtnet.c index ffc349a..6f00dfb 100644 --- a/sys/dev/virtio/network/if_vtnet.c +++ b/sys/dev/virtio/network/if_vtnet.c @@ -2470,9 +2470,9 @@ vtnet_rx_filter_mac(struct vtnet_softc *sc) sglist_init(sg, 4, segs); error |= sglist_append(sg, hdr, sizeof(struct virtio_net_ctrl_hdr)); error |= sglist_append(sg, filter-vmf_unicast, - sizeof(struct vtnet_mac_table)); + sizeof(uint32_t) + ETHER_ADDR_LEN*filter-vmf_unicast.nentries); error |= sglist_append(sg, filter-vmf_multicast, - sizeof(struct vtnet_mac_table)); + sizeof(uint32_t) + ETHER_ADDR_LEN*filter-vmf_multicast.nentries); error |= sglist_append(sg, ack, sizeof(uint8_t)); KASSERT(error == 0 sg.sg_nseg == 4, (error adding MAC filtering message to sglist)); Any virtio guru here to comment on this?

What are the issues with installing this on 9.1? Is it possible? I don't think it is recommended to use a HEAD (10) kernel with a 9.1 userland. You can always install a 9.1 and then do a full update with the source on my repository. Actually in FreeBSD, it is possible to run an older userland on a newer kernel, and a lot of effort is spent in preserving this type of backwards compatibility. So a 9.1 userland with a 10 kernel will work. However, running a newer userland on an older kernel is not guaranteed to work. So running a 10 userland with a 9.1 kernel will most likely not work. However, since you guys are doing very cutting edge stuff with 10-CURRENT, it is better that you do not waste time with 9.1. I recommend you start with a 10.0 CURRENT snapshot ISO and go from there. I am going through a similar setup exercise with a Google Summer of Code student where he needs to have a latest CURRENT system running in a VM. I wrote this blog post: http://blogs.freebsdish.org/rodrigc/2013/05/24/setting-up-a-vm-for-doing-gsoc-work/ for the steps how to do it. You can follow those steps to get bootstrapped with a working environment if it helps you out.
