I ran into this because I went to a hotel that had DHCP renew every 300 seconds, trying to download something inside the VM was getting clobbered...<\/p>\n\n\n\n
If you check your syslog or kern.log and see the following entries; then I might have the solution for you:<\/p>\n\n\n\n
kernel: [235397.022939] userif-3: sent link down event.
kernel: [235397.022943] userif-3: sent link up event.<\/p>\n\n\n\n
Then the issue is one that when your DHCP renews it calls into the kernel with the new information; unfortunately this causes VMWare Workstation & Player (might effect other VMWare products?) to reset its network stack, even though nothing changed... <\/p>\n\n\n\n
The solution after a lot of time googling different terms and trying to figure out what exactly was going on. I finally found it here (by Jan Just Keijer): To make sure the information doesn't just disappear in the future (and so I can easily find it myself) I'm going to quote the relevant code and\/or modifications I did..<\/p>\n\n\n\n Extract the This will eliminate the linkdown events; which disconnect the internet from the VMWare network driver... <\/p>\n\n\n\n After you do that; recreate the vmnet-only.tar and replace the original. Then you can run: If you still see \" sent link down event.\" in your logs; then the patch wasn't applied properly.<\/p>\n\n\n\n There is also a GitHub issue<\/a> for this issue, that has been sitting open since early 2022. It is unlikely this issue will be fixed unless there is a lot of people thumb upping that they run into this...<\/p>\n\n\n\n Finally, you can also clone the latest vmware network modules source code (you still have to apply this patch) from https:\/\/github.com\/mkubecek\/vmware-host-modules<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" I ran into this because I went to a hotel that had DHCP renew every 300 seconds, trying to download something inside the VM was getting clobbered...
