Can't block-attach a file on a read only volume?
Hi All,
One more weird issue, this works on old xen but fails on 4.4:
xendev01 ~ # mkdir /mnt/test
xendev01 ~ # mount -t tmpfs - /mnt/test
xendev01 ~ # dd if=/dev/null of=/mnt/test/disk seek=100M bs=1

Seeing dropped packets / tcp retrans on latest 4.4.1-10el6
Hi All,
Was troubleshooting some odd VM network issues and discovered that we're seeing dropped packets + retransmissions across multiple domU OS's and dom0 hardware platforms.
xendev01 ~ # tshark -R "tcp.analysis.retransmission " -i vif7.0
Running as user "root" and group "root". This could be dangerous.
