RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:


Version-Release number of selected component (if applicable):
qemu-kvm-0.12.1.2-2.293.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1. cmd
-device virtio-serial-pci,id=virtio-serial-pci0 \

-chardev socket,path=/tmp/virtio-console-3XQGtS0,id=vs0,server,nowait \
-device virtserialport,chardev=vs0,name=serialport-0,id=serialport-0,bus=virtio-serial-pci0.0 \

-chardev socket,path=/tmp/virtio-console-3XQGtS1,id=vs1,server,nowait \
-device virtserialport,chardev=vs1,name=serialport-1,id=serialport-1,bus=virtio-serial-pci0.0

2. in host
# dd if=/dev/zero of=/root/file bs=1M count=1024 
# echo /root/file | nc -U /tmp/virtio-console-3XQGtS0

3. in guest
# cat /dev/virtio-ports/serialport-0 > bak
  
Actual results:
# md5sum bak 
4220a50fc53acd4abdea136bc42ec656  bak

# md5sum file 
cd573cfaace07e7949bc0c46028904ff  file

Expected results:


Additional info:

FYI, similar bugs
Bug 677886 - MD5 of file is different from the original one after transferred via virtio serial 
Bug 702611 - Some files were not integrated after transferring four files from host to guest

Appears to be the same issue reported in Bug 677886. I've added your testcase there, so closing this as a dupe.
