VM crash with memory hotplug

Building newer qemus with the above commit reverted will be difficult because there have been a couple more changes in there which would conflict.

However, the output you posted is useful and helped me spot a not so obvious change that happened with the above commit which seems accidental.
I have a patch I'd like you to test and pushed it to a branch on github.


You can checkout the branch this way:
Reset the bisect state first:
Code:
$ git bisect reset
Add the repository and fetch its branches:
Code:
$ git remote add wbumiller 
$ git fetch wbumiller
Checkout the branch:
Code:
$ git checkout wbumiller/virtqueue-count-fix
Then build & test.
If this fixes the issue for you I'd forwad the patch to the qemu developer list for them to review and apply. (Also let me know if I should include a `Reported-by` tag with your name in the message, see the various entries in `git log` for what that would look like (I'd need a name & email address)).

Since this is based on our current 2.9.1 branch it would also be useful to verify that it fails without the patch:
Code:
$ git checkout wbumiller/extra
This one should fail.

Hi,

I tried to compile according those instructions, however it failed:
Code:
/root/qemu/crypto/tlscreds.c:180:6: error: no previous prototype for 'qcrypto_tls_creds_is_pve' [-Werror=missing-prototypes]
 bool qcrypto_tls_creds_is_pve(QCryptoTLSCreds *creds)
      ^~~~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
/root/qemu/rules.mak:69: recipe for target 'crypto/tlscreds.o' failed
make: *** [crypto/tlscreds.o] Error 1

Best regards,
Maksim
 
it's in the public pvetest repo now, pve-qemu-kvm 2.9.1-2
