Re: [libvirt] [PATCH] Revert "tpm: Check TPM XML device configuration changes after edit"

Redefining a domain via virDomainDefineXML should not give different results based on an already existing definition. Also, there's a crasher somewhere in the code: https://bugzilla.redhat.com/show_bug.cgi?id=1739338 This reverts commit 94b3aa55f83ada33a9fdda66068d58ef1a56c0a5 --- src/conf/domain_conf.c | 56 --------------------------------------- src/conf/domain_conf.h | 3 --- src/libvirt_private.syms | 1 - src/qemu/qemu_driver.c | 28 -------------------- src/qemu/qemu_extdevice.c | 2 +- src/qemu/qemu_extdevice.h | 3 --- 6 files changed, 1 insertion(+), 92 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 0456369d55..f54acd0c2a 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -31461,59 +31461,3 @@ virDomainGraphicsNeedsAutoRenderNode(const virDomainGraphicsDef *graphics) return true; } - - -static int -virDomainCheckTPMChanges(virDomainDefPtr def, - virDomainDefPtr newDef) -{ - bool oldEnc, newEnc; - - if (!def->tpm) - return 0; - - switch (def->tpm->type) { - case VIR_DOMAIN_TPM_TYPE_EMULATOR: - if (virFileExists(def->tpm->data.emulator.storagepath)) { - /* VM has been started */ - /* Once a VM was started with an encrypted state we allow - * less configuration changes. - */ - oldEnc = def->tpm->data.emulator.hassecretuuid; - if (oldEnc && def->tpm->type != newDef->tpm->type) { - virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", - _("Changing the type of TPM is not allowed")); - return -1; - } - if (oldEnc && !newDef->tpm) { - virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", - _("Removing an encrypted TPM is not allowed")); - return -1; - } - newEnc = newDef->tpm->data.emulator.hassecretuuid;
