Greetings, Working with XCP 1.0 here. I have the problem of losing disk space upon creating snapshots. I''ve been through the XenServer forums and have tried using the leaf-coalesce tool, but it doesn''t seem to work that great, since I have to take my VMs offline and that doesn''t work. Does anybody have any answers on how to reclaim this disk space? We

Hello Rusty, I think I have found a problem in the virtio network driver. virtio_net reclaims sent skbs on xmit. That means that there is always one skb outstanding and the netdev packet statistic is always one packet to low. Documentation/networking/drivers.txt says 3) Do not forget that once you return 0 from your hard_start_xmit method, it is your driver's responsibility to free up

Of course, this is usually called from an

From: Mark McLoughlin <markmc at redhat.com> hdr->csum_start is the offset from the start of the ethernet header to the transport layer checksum field. skb->csum_start is the offset from skb->head. skb_partial_csum_set() assumes that skb->data points to the ethernet header - i.e. it computes skb->csum_start by adding the headroom to hdr->csum_start. Since
