Package: virtualbox-ose Version: 3.2.0-dfsg-1 Severity: normal My VirtualBox instances have recently started losing incoming packets from the host after about 2 MB transmitted. I'm using dput to upload packages from the Sid host to a Lenny guest, so several files are uploaded in succession through SCP. Small files get transmitted almost instantaneously, as expected, but larger ones seem to get the first 2 MB transmitted in an initial burst, then the rest goes very slowly (typical transfer speeds around 30 kB/s). I've tried running the following:
,---- | watch "netstat -s | grep 'retransmit\|los'" `---- On the host, I get large (and fast-growing) numbers for "segments retransmited", "times recovered from packet loss by selective acknowledgements", "TCP data loss events", "fast retransmits" and "retransmits in slow start". The same statistics are very small on the guest, and not moving. An SCP from a different box on the same network to the guest doesn't exhibit packet loss. Neither does SCPing from the guest to the host. I'm using bridged networking, with a DHCP server on the LAN, no firewalling on either host or guest. It might be relevant to note that I don't have hardware virtualization support in my fairly old Athlon CPU. Downgrading virtualbox-ose and virtualbox-ose-dkms (and virtualbox-ose-qt, for completeness's sake) to 3.1.8-dfsg-1 fixes the problem. Please tell me if I can help debugging in any way.
