The following reply was made to PR kern/104056; it has been noted by GNATS. From: Jonas Nagel <fireball@zerouptime.ch> To: Astrodog <astrodog@gmail.com> Cc: bug-followup@FreeBSD.org Subject: Re: kern/104056: VMware ESX 3.0: lnc0: Missed packet -- no receive buffer Date: Mon, 09 Oct 2006 00:38:09 +0200 Never mind my last mail; I was able to install the tools through the ports. I used the vmware-guestd5 port, since I don't run X on that VM. It wouldn't install the vmxnet.ko though by default. There is also only one precompiled for FreeBSD 5.3 on the ISO; I copied it over and it loaded fine. dns1# ll vmxnet.ko -r-xr-xr-x 1 root wheel 12837 Oct 8 23:59 vmxnet.ko dns1# kldstat Id Refs Address Size Name 1 5 0xc0400000 6f0e44 kernel 2 1 0xc0af1000 59f00 acpi.ko 3 1 0xc5f0e000 3000 vmmemctl.ko 4 1 0xc5f11000 4000 vmxnet.ko dns1# ps ax |grep vmware 85086 ?? Ss 0:01.93 /usr/local/sbin/vmware-guestd --background /var/run/vmware_guestd.pid --halt-command I even put the said vmxnet.ko into /boot/kernel and loaded it using 'vmxnet_load="YES"'. But this all didn't have any influence over network performance. Specially the connection to other virtual machines is less than acceptable. Also note the interesting pattern: dns1# ping -s 16000 hirtdco01 PING hirtdco01.hirtdom.local (10.0.0.90): 16000 data bytes 16008 bytes from 10.0.0.90: icmp_seq=0 ttl=128 time=2.148 ms 16008 bytes from 10.0.0.90: icmp_seq=1 ttl=128 time=1.854 ms 16008 bytes from 10.0.0.90: icmp_seq=2 ttl=128 time=878.200 ms 16008 bytes from 10.0.0.90: icmp_seq=3 ttl=128 time=1.963 ms 16008 bytes from 10.0.0.90: icmp_seq=4 ttl=128 time=1007.225 ms 16008 bytes from 10.0.0.90: icmp_seq=5 ttl=128 time=2.003 ms 16008 bytes from 10.0.0.90: icmp_seq=6 ttl=128 time=1007.256 ms 16008 bytes from 10.0.0.90: icmp_seq=7 ttl=128 time=167.444 ms 16008 bytes from 10.0.0.90: icmp_seq=8 ttl=128 time=2.328 ms 16008 bytes from 10.0.0.90: icmp_seq=9 ttl=128 time=1.985 ms (...) --- hirtdco01.hirtdom.local ping statistics --- 88 packets transmitted, 81 packets received, 7% packet loss round-trip min/avg/max/stddev = 1.581/298.857/1010.492/417.300 ms It goes from 1-2 ms up to 1 second and down again or, well, results into timeouts. Any other idea (besides blaming it to VMware)? -- Jonas Nagel <fireball@zerouptime.ch>
