Patch 1: Extend BaseTestBusyMigration to migrate multiple VMs concurrently. Source/destination pairs go from the edges to the center (VM0->VM(N-1), VM1->VM(N-2), ...). Save and load use two-phase async operations: all migrations start first, then each one is polled for completion. The IGT workload runs on every source VM. The single-VM (same source and destination VF) flow is kept. For odd VM counts, the center VM is not migrated. Patch 2: Skip double migration tests when the debugfs 'resfix_stoppers' hook isn't available (KMD no-debug build), instead of failing them. Patch 3: Reconfigure the tests setup: - switch basic and migration test variants to auto resources and scheduling provisioning - drop the 'full' migration variant; busy migration tests 1xVF and 2xVF config scope by default - add TestBusyMigrationParallel with 4xVF and 6xVF variants, which uses the parallel migration support from patch 1 - remove the manual EQ/PT override in test_2vm_pause_resume, which is no longer needed since the driver provides finite defaults - limit TestVfDriverLoadRemove to 2 VMs to avoid exhausting host memory on systems with limited host RAM (<=16GB) Signed-off-by: Adam Miszczak Cc: Marcin Bernatowicz Cc: Kamil Konieczny Adam Miszczak (3): tools/vmtb: Support parallel multi-VM busy migration tools/vmtb: Skip double migration tests on no-debug config tools/vmtb: Reconfigure tests setup tools/vmtb/vmm_flows/test_basic.py | 15 +- tools/vmtb/vmm_flows/test_migration.py | 235 ++++++++++++++++--------- 2 files changed, 157 insertions(+), 93 deletions(-) -- 2.39.1
