[Qemu-devel] [Bug 1636217] Re: qemu-kvm 2.7 does not boot kvm VMs with virtio on top of VMware ESX |

Hi,
I have exactly the same problem.
My stack:
- macOS Sierra 10.12.6
- VMware Fusion 10.1.1 (tried with 10.0.1 too)
- Linux 4.9.78 (tried with 4.9.65 too)
- Qemu 2.11.0 (tried with 2.10.1 too)
All is working great with i440fx (or q35) <= 2.6 but it doesn't boot on
>= 2.7 and QEMU takes all the CPU.
It doesn't boot with the disk in virtio and scsci-virtio mode but boot
in scsi.
Exactly the same configuration on a baremetal (so no macOS and VMware)
works great.
So I assume it's a bug with VMware and virtio.

Title:
qemu-kvm 2.7 does not boot kvm VMs with virtio on top of VMware ESX
Status in QEMU:
New
Bug description:
After todays Proxmox update all my Linux VMs stopped booting.
# How to reproduce
- Have KVM on top of VMware ESX (I use VMware ESX 6)
- Boot Linux VM with virtio Disk drive.
# Result
virtio based VMs do not boot anymore:
address@hidden:/etc/pve/nodes/demotuxdc/qemu-server# grep virtio0 100.conf
bootdisk: virtio0
virtio0: pvestorage:100/vm-100-disk-1.raw,discard=on,size=20G
(initially with cache=writethrough, but that doesn´t matter)
What happens instead is:
- BIOS displays "Booting from harddisk..."
- kvm process of VM loops at about 140% of Intel(R) Core(TM) i5-6260U CPU @
1.80GHz Skylake dual core CPU
Disk of course has valid bootsector:
address@hidden:/srv/pvestorage/images/100# file -sk vm-100-disk-1.raw
vm-100-disk-1.raw: DOS/MBR boot sector DOS/MBR boot sector DOS executable
(COM), boot code
address@hidden:/srv/pvestorage/images/100# head -c 2048 vm-100-disk-1.raw |
hd | grep GRUB
00000170 be 94 7d e8 2e 00 cd 18 eb fe 47 52 55 42 20 00 |..}.......GRUB .|
# Workaround 1
- Change disk from virtio0 to scsi0
- Debian boots out of the box after this change
- SLES 12 needs a rebuilt initrd
- CentOS 7 too, but it seems that is not even enough and it still fails (even
in hostonly="no" mode for dracut)
# Workaround 2
Downgrade pve-qemu-kvm 2.7.0-3 to 2.6.2-2.
# Expected results
Disk boots just fine via virtio like it did before.
# Downstream bug report
Downstream suggests an issue with upstream qemu-kvm:
