I have a host CentOS 7.6 machine. On that machine VMs are created using Virtual Manager. VM also has CentOS 7.4. We have made passthrough from the VM to the host OS.
Certain UDP Checksum errors are received leading to host server crashing. Rx & Tx checksumming is off.
Please help to resolve this issue.
UDP Checksum Errors Leading to OS Crash
Re: UDP Checksum Errors Leading to OS Crash
Neither 7.4 nor 7.6 are supported. Run yum update to get to the latest point release, 7.9.2009, plus all more recent fixes.
CentOS 7.4 is 4 whole years out of date, 7.6 is "only" 3 years out of date.
There are more than 12,500 lines in the kernel rpm changelog since the 7.6 kernel 3.10.0.-957 and there are more than 36,000 changes since the 7.4 kernel. Many of those fix important and critical CVEs that you need to put on to keep your systems secure. There are 790 mentions of the string "CVE" in those 36,000 entries and 363 in the one for thse 7.6 kernel. Those are documented, known exploits that are on your system now and need to be fixed. And that doesn't include the possibility that your problem is one of the other 34,999 items on the list.

The future appears to be RHEL or Debian. I think I'm going Debian.

No. The point is ONLY 7.9 is a supported version. Anything less than 7.9 and we will tell you to upgrade.Can you please share release notes where this bug is resolved.
Run yum update. Get to a supported version. Try again.
