The error is that we run a very simple rpm command in the guest and it fails rather badly: # rpm -ql kernel error: rpmdb: BDB0113 Thread/process 12680/139878611654464 failed: BDB1507 Thread died in Berkeley DB library error: db5 error(-30973) from dbenv->failchk: BDB0087 DB_RUNRECOVERY: Fatal error, run database recovery error: cannot open Packages index using db5 - (-30973) error: cannot open Packages database in /var/lib/rpm error: rpmdb: BDB0113 Thread/process 12680/139878611654464 failed: BDB1507 Thread died in Berkeley DB library error: db5 error(-30973) from dbenv->failchk: BDB0087 DB_RUNRECOVERY: Fatal error, run database recovery error: cannot open Packages database in /var/lib/rpm Is the rhel7-rc-graphics guest OK? Obviously it cannot be running because we check for that. You could try booting up the guest and running various simple rpm commands like 'rpm -ql kernel' and 'rpm -qa' and just check that the RPM database really isn't corrupt. (In reply to Richard W.M.

Yes,it is ok,after conversion,I can boot it successfully. > You could try booting up the guest and running various simple > rpm commands like 'rpm -ql kernel' and 'rpm -qa' and just check > that the RPM database really isn't corrupt. I tried these commands,it worked fine. btw,I can not reproduce this error everytime for the same guest,there is a rhel6 bug 806714 in old v2v for reference. I think I see what's going on. I have pushed these patches which I hope will fix things (virt-v2v >= 1.27.50): https://github.com/libguestfs/libguestfs/commit/6db2ff52f9557bc3644700386320dc7a3fa54830 https://github.com/libguestfs/libguestfs/commit/4aa38bba2ca77cf0ff7271a8f419182c57f59f7a Reproduce this bug with: libguestfs-1.27.49-1.1.el7.x86_64 virt-v2v-1.27.49-1.1.el7.x86_64 1.Prepare a guest,do some operations to make the rpmdb corrupted. # yum install libvirt error: rpmdb: BDB0113 Thread/process 3350/140483719948096 failed: BDB1507 Thread died in Berkeley DB library error: db5 error(-30973) from dbenv->failchk: BDB0087 DB_RUNRECOVERY: Fatal error, run database recovery error: cannot open Packages index using db5 - (-30973) error: cannot open Packages database in /var/lib/rpm CRITICAL:yum.main: Error: rpmdb open failed 2.Use virt-v2v to convert the guest,error shows: # virt-v2v -ic xen+ssh://10.66.106.64 -o rhev -os 10.66.90.115:/vol/v2v_auto/auto_export --network rhevm rhel7-rc-graphics -of raw [ 0.0] Opening the source -i libvirt -ic xen+ssh://10.66.106.64 rhel7-rc-graphics [ 16.0] Creating an overlay to protect the source from being modified [ 30.0] Opening the overlay [ 230.0] Initializing the target -o rhev -os 10.66.90.115:/vol/v2v_auto/auto_export [ 230.0] Inspecting the overlay [ 245.0] Checking for sufficient free disk space in the guest [ 245.0] Estimating space required on target for each disk [ 245.0] Converting Red Hat Enterprise Linux Server release 7.0 (Maipo) to run on KVM virt-v2v: error: libguestfs error: command_lines: error: rpmdb: BDB0113 Thread/process 3350/140483719948096 failed: BDB1507 Thread died in Berkeley DB library error: db5 error(-30973) from dbenv->failchk: BDB0087 DB_RUNRECOVERY: Fatal error, run database recovery error: cannot open Packages index using db5 - (-30973) error: cannot open Packages database in /var/lib/rpm error: rpmdb: BDB0113 Thread/process 3350/140483719948096 failed: BDB1507 Thread died in Berkeley DB library error: db5 error(-30973) from dbenv->failchk: BDB0087 DB_RUNRECOVERY: Fatal error, run database recovery error: cannot open Packages database in /var/lib/rpm If reporting bugs, run virt-v2v with debugging enabled and include the complete output: virt-v2v -v -x [...] Tested with latest virt-v2v version: libguestfs-1.27.50-1.1.el7.x86_64 virt-v2v-1.27.50-1.1.el7.x86_64 Repeat the above steps,no such error shows.
