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.

2. inside of guest:

diskpart
sel disk 1        -> this is the emulated usb
create part pri   -> create a primary partition
format fs=ntfs label=usb -> format it as NTFS, sector by sector, without the laziness 'quick' option

3. migrate this vm

migrate -d tcp:xx:yy


Actual results:

guest bsod in few min
should be able to see the minidump in C:\windows\minidump

Expected results:
both host and guest work well

CRITICAL_STRUCTURE_CORRUPTION (109)
This bugcheck is generated when the kernel detects that critical kernel code or
data have been corrupted. There are generally three causes for a corruption:
1) A driver has inadvertently or deliberately modified critical kernel code
 or data. See http://www.microsoft.com/whdc/driver/kernel/64bitPatching.mspx
2) A developer attempted to set a normal kernel breakpoint using a kernel
 debugger that was not attached when the system was booted. Normal breakpoints,
 "bp", can only be set if the debugger is attached at boot time. Hardware
 breakpoints, "ba", can be set at any time.
3) A hardware corruption occurred, e.g. failing RAM holding kernel code or data.

Hmm, that doesn't look usb-storage related at all.
Probably formating usb-storage just creates some load
which increases the chance to hit this.

Cc'ing paolo.
Comment 7 Paolo Bonzini 2015-09-22 22:21:02 UTC 
The first three arguments are "reserved", but they strongly look like old value, new value (or a hash of it) and MSR index.  In fact the third is definitely the MSR index and it is MSR_TSC_AUX.

Do you remember if the crash happened before migration finished, or afterwards?
Comment 8 Paolo Bonzini 2015-09-22 22:22:15 UTC 
It looks like QEMU is not saving and restoring MSR_TSC_AUX.

not sure :(
I was started the formatting in guest and type 'migrate -d ' in qemu monitor and leave a while, when I back, the cmd terminal in guest is gone, so I check if it has a dump and it's there.

then I tried to reproduce as C#1, but failed, with 4 attempts with exactly identical steps, on origin host. no luck .
