Hey, two questions regarding setwd and list.files: I try to use the function list.files: >datapath<-'/nfs/home/m/cremer/gaw/data/traws_chrs' >fl<-list.files(datapath, pattern="\\.tped") but I get the following error message: Warning message: In list.files(datapath, pattern = "\\.tped") : list.files: '/nfs/home/m/cremer/gaw/data/traws_chrs/'

Hello: I have problems generating big JPG plots in functions. the following code runs fine in the script: #### runs fine in script, generate 40k "test1.jpg" in the given directory plotPlatesAlong <- c(1:5) plotDirPath <- paste(dataPath, "OutputPlots\\", sep="") filename <- paste(plotDirPath,"test1.jpg", sep="") jpeg(file=filename)

This patch enables virtio_net to switch over to a VF datapath when a VF netdev is present with the same MAC address. It allows live migration of a VM with a direct attached VF without the need to setup a bond/team between a VF and virtio net device in the guest. The hypervisor needs to enable only one datapath at any time so that packets don't get looped back to the VM over the other

This patch enables virtio_net to switch over to a VF datapath when STANDBY feature is enabled and a VF netdev is present with the same MAC address. It allows live migration of a VM with a direct attached VF without the need to setup a bond/team between a VF and virtio net device in the guest. It uses the API that is exported by the net_failover driver to create and and destroy a master failover

This patch enables virtio_net to switch over to a VF datapath when a VF netdev is present with the same MAC address. It allows live migration of a VM with a direct attached VF without the need to setup a bond/team between a VF and virtio net device in the guest. The hypervisor needs to unplug the VF device from the guest on the source host and reset the MAC filter of the VF to initiate failover

VF. Although there are 2 datapaths to the device, the hypervisor will enable only one at any time.? The virtio via PF datapath is only enabled during live migration when the VF is unplugged. If not, VF broadcasts/multicasts will get looped back to the VM via the PF datapath. In the RFC path i was assuming that the VM can use bot...

Since UFO6 packets can now be identified by SKB_GSO_UDP6, add proper checks to handel UFO6 flows. Legacy applications may still have UFO6 packets identified by SKB_GSO_UDP, so we need to continue to handle them correclty.

For the driver it self, it should not be hard. But I think you mean the issue of e.g virtio_vsock_pkt itself which doesn't support sg. For short time, maybe we can use kvec instead.
