[Qemu-devel] [Bug 1817268] Re: Input/output error during migration
Hi David, Thanks you for your help. The VARS file is 128K. I increased the "/var/lib/libvirt/qemu/nvram/testuefi_VARS.fd" var file to 1M, but had this error during migration: error: internal error: qemu unexpectedly closed the monitor: 2019-02-22T09:52:34.098833Z qemu-system-x86_64: Length mismatch: system.flash1: 0x10 in != 0x2: Invalid argument 2019-02-22T09:52:34.098940Z qemu-system-x86_64: error while loading state for instance 0x0 of device 'ram' So I destroyed the machine, removed the "/var/lib/libvirt/qemu/nvram/testuefi_VARS.fd" var file, increased the /usr/share/OVMF/OVMF_VARS.fd file in both hypervisors (src and dest) to 1M, recreated the machine and now the migration works: virsh migrate --verbose --live --p2p --tunnelled --copy-storage-inc --change-protection --abort-on-error testuefi qemu+tcp:///system Migration: [100 %] I still have to test if increasing the VARS file do not cause issues on the virtual machine. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1817268 Title: Input/output error during migration Status in QEMU: New Bug description: Operating system: Ubuntu 18.04.2 LTS qemu version: 2.11.1, but also reproduced with 3.1.0 (compiled manually). virsh --version: 4.0.0 Hello, I am having an issue with migration of UEFI virtual machines.

[Qemu-devel] [Bug 1817268] Re: Input/output error during migration
Hi Mathieu, How big is your testuefi-VM_VARS.fd file ? Does the problem go away if you pad it to 1MB? I've seen a problem migrating pflash where the files aren't 1MB (?) multiples but only using the 'old style' block migration; normally you get an NBD based block migration but when you select tunneling libvirt can't tunnel the nbd stream so falls back to the old style migration and hits this bug. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1817268 Title: Input/output error during migration Status in QEMU: New Bug description: Operating system: Ubuntu 18.04.2 LTS qemu version: 2.11.1, but also reproduced with 3.1.0 (compiled manually). virsh --version: 4.0.0 Hello, I am having an issue with migration of UEFI virtual machines.
