016a62 |
Instead of re-using the get_opt_name() method from QemuOpts to split a
|
|
|
016a62 |
string on ':', just use g_strsplit().

RHEL8 notes:
|
|
|
016a62 |
|
|
|
016a62 |
- Fix up upstream's obviously garbled UTF8 sequences in Dan's name (Author
|
|
|
016a62 |
meta-datum, Signed-off-by tags).
|
|
|
016a62 |
|
|
|
016a62 |
- Harmless context difference due to downstream-only commit 8b53513834e6
|
|
|
016a62 |
("Use kvm by default", 2018-04-24).
